Abstract
OBJECTIVE To prospectively evaluate the disease course and the performance of clinical, patient-reported outcome (PRO) and musculoskeletal ultrasound measures in patients with polymyalgia rheumatica (PMR). METHODS The study population included 85 patients with new-onset PMR who were initially treated with prednisone equivalent dose of 15 mg daily tapered gradually, and followed for 26 weeks. Data collection included physical examination findings, laboratory measures of acute-phase reactants, and PRO measures. Ultrasound evaluation was performed at baseline and Week 26 to assess for features previously reported to be associated with PMR. Response to corticosteroid treatment was defined as 70% improvement in PMR on visual analog scale (VAS). RESULTS At baseline, 77% had hip pain in addition to shoulder pain and 100% had abnormal C-reactive protein or erythrocyte sedimentation rate. On ultrasound, 84% had shoulder findings and 32% had both shoulder and hip findings. Response to corticosteroid treatment occurred in 73% of patients by Week 4 and was highly correlated with percentage improvement in other VAS measures. Presence of ultrasound findings at baseline predicted response to corticosteroids at 4 weeks. Factor analysis revealed 6 domains that sufficiently represented all the outcome measures: PMR-related pain and physical function, an elevated inflammatory marker, hip pain, global pain, mental function, and morning stiffness. CONCLUSION PRO measures and inflammatory markers performed well in assessing disease activity in patients with PMR. A minimum set of outcome measures consisting of PRO measures of pain and function and an inflammatory marker should be used in practice and in clinical trials in PMR.

Abstract
OBJECTIVE To present the published data concerning the US assessment of tendon lesions as well as the US metric properties investigated in inflammatory arthritis. METHODS A systematic literature search of PubMed, Embase and the Cochrane Library was performed. Selection criteria were original articles in the English language reporting US, Doppler, tenosynovitis and other tendon lesions in patients with RA and other inflammatory arthritis. Data extraction focused on the definition and quantification of US-detected tenosynovitis and other tendon abnormalities and the metric properties of US according to the OMERACT filter for evaluating the above tendon lesions. RESULTS Thirty-three of 192 identified articles were included in the review. Most articles were case series (42%) or case-control (33%) studies describing hand and/or foot tenosynovitis in RA patients. The majority of older articles used only B-mode, whereas the most recent studies have incorporated Doppler mode. Definition of tenosynovitis or other tendon lesion was provided in 70% of the evaluated studies. Most of the studies (61%) used a binary score for evaluating tendon abnormalities. Concerning the OMERACT filter, 24 (73%) articles dealt with construct validity. The comparator most commonly used was clinical assessment and MRI. There were few studies assessing criterion validity. Some studies evaluated reliability (36%), responsiveness (21%) and feasibility (12%). CONCLUSION US seems a promising tool for evaluating inflammatory tendon lesions. However, further validation is necessary for implementation in clinical practice and trials.

Abstract
OBJECTIVE Musculoskeletal US is being increasingly used for the assessment of synovitis, although questions remain about its reliability. One potential factor affecting reliability is the lack of consensus of image acquisition methods such as using different joint positions. This may have an implication on the reproducibility of studies that use US as an outcome measure. The aim of this study was to determine whether a change in joint position might significantly alter the quantification of US-detected synovitis in patients with inflammatory arthritis (IA). METHODS IA patients with clinically swollen wrists, MCP and/or knee joints were recruited. These joints were assessed quantitatively for the presence of synovitis when they were placed in different positions. RESULTS Seventy-five patients with IA were assessed. The greatest grey scale (GS) and power Doppler (PD) scores for the MCP joints were found in the flat (0°) position (91 and 100% of cases, respectively) compared with other positions (P < 0.001). Similar results were found in the wrist joints. The greatest GS and PD scores for the knee joint were found in 30° flexion [100 and 95.6% of cases, respectively, compared with other positions (P < 0.001)]. The inter- and intra-reader reliability was good to excellent. CONCLUSION The position in which a joint is scanned for synovitis appears to significantly influence the US assessment of synovitis. Our study suggests that the standardized scanning of the hand joints in a flat position and the knees in a 30° position are associated with the highest GS and PD scores.

Abstract
Previous cadaveric studies have suggested that forefoot deformities at the metatarsophalangeal (MTP) joints in patients with rheumatoid arthritis (RA) might result from the failure of the ligamentous system and displacement of the plantar plates. This study aimed to examine the relationship between plantar plate pathology and the rheumatoid arthritis magnetic resonance imaging score (RAMRIS) of the lesser (second to fifth) MTP joints in patients with RA using high-resolution 3 T magnetic resonance imaging (MRI). In 24 patients with RA, the forefoot was imaged using 3 T MRI. Proton density fat-suppressed, T2-weighted fat-suppressed and T1-weighted post gadolinium sequences were acquired through 96 lesser MTP joints. Images were scored for synovitis, bone marrow oedema and bone erosion using the RAMRIS system and the plantar plates were assessed for pathology. Seventeen females and 7 males with a mean age of 55.5 years (range 37–71) and disease duration of 10.6 years (range 0.6–36) took part in the study. Plantar plate pathology was most frequently demonstrated on MRI at the fifth MTP joint. An association was demonstrated between plantar plate pathology and RAMRIS-reported synovitis, bone marrow oedema and bone erosion at the fourth and fifth MTP joints. In patients with RA, 3 T MRI demonstrates that plantar plate pathology at the lesser MTP joints is associated with features of disease severity. Plantar plate pathology is more common at the fourth and fifth MTP joints in subjects with RA in contrast to the predilection for the second MTP reported previously in subjects without RA.

Abstract
Introduction An increasing number of studies have applied ultrasound to the evaluation of entheses in spondyloarthritis patients. However, no clear agreement exists on the definition of enthesitis, on the number and choice of entheses to examine and on ultrasound technique, which may all affect the results of the examination. The objectives of this study were to first determine the level of homogeneity in the ultrasound definitions for the principal lesions of enthesitis in the published literature and second, to evaluate the metric properties of ultrasound for detecting enthesitis according to the OMERACT filter. Methods Search was performed in PUBMED and EMBASE. Both grey-scale and Doppler definitions of enthesitis, including describing features of enthesitis, were collected and metrological qualities of studies were assessed. Results After selection, 48 articles were analyzed. The definition of ultrasound enthesitis and elementary features varied among authors. Grey-scale enthesitis was characterized by increasing thickness (94% of studies), hypoechogenicity (83%), enthesophytes (69%), erosions (67%), calcifications (52%), associated bursitis (46%) and cortical irregularities (29%). Only 46% of studies reported the use of Doppler. High discrepancies were observed on frequency, type of probe and Doppler mode used. Face and content validity were the most frequently evaluated criteria (43%) followed by reliability (29%) and responsiveness (19%). Conclusions Ultrasound has evidence to support face, content validity and reliability for the evaluation of enthesitis, though there is a lack of well-reported methodology in most of the studies. Consensus on elementary lesions and standardization of exam is needed to determine the ultrasound definition of enthesitis in grey-scale and in Doppler for future applications.

Abstract
OBJECTIVES To determine whether non-steroidal anti-inflammatory drugs (NSAIDs) have a significant effect on ultrasonographic (US) grey scale (GS) and power Doppler (PD) assessment of synovitis in rheumatoid arthritis (RA). METHODS Patients with RA taking NSAIDs were randomised to either stopping (for a minimum of 5 drug half-lives) or continuing the drug. All patients had a clinical assessment and US examination of both hands and wrists before and after stopping/continuing the NSAID. Changes at follow-up were compared between groups using Mann-Whitney U tests. RESULTS A total of 58 patients with RA were recruited. All the clinical assessment parameters (including disease activity, pain, general state of health and physician global visual analogue score and tender and swollen joints count) showed an increase in the group who stopped their NSAID treatment. The total GS and PD score showed median (first to third quartiles) increase of 9.5 (5.75 to 19.0) and 4.0 (2.0 to 6.0) per patient, respectively, in the patients who stopped their NSAID in comparison with 1.0 (-1.0 to 2.25) and 0.0 (-2.0 to 3.0), respectively, in the patients who continued their NSAID (p<0.001). There was an increase in the number of joints scoring >0 for GS and PD in the patients who stopped the NSAID. The inter- and intrareader agreement was good to excellent for the US examination. CONCLUSION NSAID usage may mask the GS and PD signal and result in lower scoring despite continuing disease activity. Consideration should be given to the NSAID effect in designing clinical studies which use US to assess response to therapeutic.

Abstract
BACKGROUND Nail disease is a characteristic manifestation of the psoriatic disease spectrum but is poorly understood. OBJECTIVE Given the intrinsically high spatial resolution imaging capabilities of optical coherence tomography (OCT), we assessed its value in psoriatic nail disease compared to high-resolution ultrasonography (US). METHODS All fingernails in a psoriatic arthritis patient with nail changes were scanned with OCT, and findings were compared with high-resolution US. RESULTS US showed loss of trilaminar appearance in all nails, resulting in the nail plate being visualized as a single hyperechoic layer with inhomogeneous thickness. The OCT images showed much higher-resolution changes with prominent thickening in the ventral plate at the nail bed which was grossly inhomogeneous, 'eroded' and irregularly fused with the underlying epidermis, which correlated with the clinical observation of subungal hyperakeratosis. CONCLUSION OCT has considerable potential for the evaluation of psoriatic nail disease and may be superior to US.

Abstract
Abstract
Background: Aromatase inhibitors (AI) are well known to be associated with troublesome musculoskeletal side effects but the underlying mechanisms are poorly understood and methods of objective assessment poorly defined. We have performed a prospective detailed evaluation of grip strength (primary endpoint), symptoms, imaging and biomarkers in patients receiving either an AI, tamoxifen or no endocrine therapy. Methods: 77 patients with early breast cancer from two specialist Breast Units were recruited prior to starting one of 4 treatment arms: upfront AI (A), switch from tamoxifen to AI (B), tamoxifen (C) and no treatment (D). Arthralgia was defined as worsening of joint pain score at 3 months and a positive Tinel's or Phalen's test was taken as evidence of carpal tunnel syndrome. Grip strength was measured (average of three readings from each hand) using a Jamar Dynamometer at baseline, 1, 2, 3, 6 and 12 months. In addition, biochemical (endocrine and collagen markers), rheumatological (inflammatory and cytokine markers) and radiological assessments of the hands (diagnostic ultrasound, bone density using DXA and plain radiograph) were performed at protocol-specified intervals. A subset of patients also underwent hand MRI at baseline, 3 and 12 months. Detailed rheumatological examination and questionnaire (DAS-28, SF-36, HAQ-DI and BPI-SF) assessment were performed at each visit. Grip strength was analysed using analysis of covariance with age, prior chemotherapy and baseline grip as covariates. The Kruskal-Wallis test was used for questionnaire data. The 3 month data on grip strength, questionnaire, clinical assessment and hand ultrasound are presented here. Results: 47 patients received an AI (34 upfront, 13 switch), 22 tamoxifen and 8 no endocrine treatment (controls). Median age (yearrs) for each group was: 62.1 (A), 51.0 (B), 65.2 (C) and 61.2 (D). The incidence of arthralgia at 3 months was 38% (A), 17% (B), 38% (C) and 14% (D). Mean baseline grip strength was similar in each arm: 22.5kg (A), 23.1kg (B), 20.2kg (C) and 23.2kg (D) (p=0.342 ANOVA). At 3 months, the mean percentage change in grip strength was +0.2% (A), +2.2% (B), +4.5% (C),+1.2% (D) (p=ns ANCOVA). In those on AI, the development of arthralgia was not shown to be associated with change in grip strength (p=0.82). Morning stiffness was also no different at 3 months. Clinical signs of carpal tunnel syndrome were evident in 10/45 (22%) of patients receiving AI therapy compared to 4/28 (14%) on tamoxifen/control. There were 4 cases of trigger thumb or finger, all in patients receiving AI treatment. Changes in HAQ-DI and pain (VAS) at 3 months were no different between groups (p=0.27, p=0.1 respectively). Ultrasound assessment of the flexor tendons at 3 month identified an increase in median score for tendon sheath fluid in those in the AI groups (3 (AI) v 1 (No AI) p=0.07, Mann-Whitney U test). There was no significant change in average median nerve cross-sectional area at 3 month.
Conclusion: This study suggests that patient reported arthalgia does not correlate with early changes in and mean grip strength. However, there may be early signs of carpal tunnel syndrome, trigger finger and fluid in the flexor tendon sheaths detectable by ultrasound.

Abstract
BackgroundEntheseal fibrocartilage (EF) derangement is hypothesised to be pivotal to the pathogenesis of spondyloarthritis. Ultrasound is useful for visualisation of the enthesis but its role in EF visualisation is uncertain. This work aimed to demonstrate face and content validity of ultrasound for EF visualisation both by bovine histological evaluation and EF imaging in spondyloarthritis.MethodsAchilles enthesis of 18 bovine hindfeet was visualised using a MyLab 70 ultrasound machine. The presence of tissue with EF characteristics was documented and histological confirmation was performed on five randomly selected sections using Masson trichrome staining. Ultrasound of the Achilles tendon (AT) was performed in 19 patients with spondyloarthritis and 21 healthy controls (HC).ResultsThe bovine EF could be visualised in all cases and seen as a thin, uncompressible, well-defined, anechoic layer between the hyperechoic bone and the hyperechoic fibrils of the enthesis both in longitudinal and transverse scans. This region corresponded to EF on histological examination. The same pattern of low signal corresponding to EF location was seen in 17/19 patients and all HC. Discontinuities of the anechoic layer around the erosions and enthesophytes were observed in the spondyloarthritis group. The thickness of the anechoic layer was not significantly different in spondyloarthritis and HC (0.5±0.1 vs 0.5±0.2 mm, p=0.9) whereas the thickness of the EF was greater in men (0.6±0.2 vs 0.5±0.1 mm; p=0.009) compared with women.ConclusionUltrasound can visualise EF of the AT insertion, which can be abnormal in cases of spondyloarthritis. This has implications for a better understanding of enthesopathy.

Abstract
OBJECTIVE Because musculoskeletal ultrasound (MSUS) is highly user dependent, we aimed to establish whether non-mentored learning of MSUS is sufficient to achieve the same level of diagnostic accuracy and scanning reliability as has been achieved by rheumatologists recognized as international experts in MSUS. METHODS A group of 8 rheumatologists with more experience in MSUS and 8 rheumatologists with less experience in MSUS participated in an MSUS exercise to assess patients with musculoskeletal abnormalities commonly seen in a rheumatology practice. Patients' established diagnoses were obtained from chart review (gout, osteoarthritis, rotator cuff syndrome, rheumatoid arthritis, and seronegative arthritis). Two examining groups were formed, each composed of 4 less experienced and 4 more experienced examiners. Each group scanned 1 predefined body region (hand, wrist, elbow, shoulder, knee, or ankle) in each of 8 patients, blinded to medical history and physical examination. Structural abnormalities were noted with dichotomous answers, and an open-ended answer was used for the final diagnosis. RESULTS Less experienced and more experienced examiners achieved the same diagnostic accuracy (US-established diagnosis versus chart review diagnosis). The interrater reliability for tissue pathology was slightly higher for more experienced versus less experienced examiners (kappa = 0.43 versus kappa = 0.34; P = 0.001). CONCLUSION Non-mentored training in MSUS can lead to the achievement of diagnostic accuracy in MSUS comparable to that achieved by highly experienced international experts. Reliability may increase slightly with additional experience. Further study is needed to determine the minimal training requirement to achieve proficiency in MSUS.

Abstract
OBJECTIVE To examine the relationship between ultrasound (US)-detected synovial pathology in hand OA and the clinical response to parenteral corticosteroids. METHODS People with symptomatic OA of the hand completed questionnaires [visual analogue scale (VAS) pain, Australian Canadian Osteoarthritis Hand Index and VAS global] and underwent an US examination of both hands prior to receiving an i.m. dose of methylprednisolone. Four- and twelve-week assessments were performed to assess therapeutic response. RESULTS Thirty-six subjects with established OA were enrolled. Twenty-four (67%) subjects met the primary end-point of a 20% reduction in VAS pain, 25 (69.4%) met the Osteoarthritis Research Society International response criteria at 4 weeks. Overall in the group, there was a reduction in levels of pain in the most painful joint, pain in all joints and in global disease activity at 4 weeks (P < 0.001, P < 0.001 and P < 0.001, respectively). Reduction in symptoms was not associated with a statistically significant reduction in US-detected synovial hypertrophy or power Doppler signal. CONCLUSIONS In this observational study, parenteral corticosteroids were associated with a statistically significant reduction in symptoms, but no statistically significant reduction in US-detected synovial inflammation. The latter finding may, however, reflect the relatively low levels of synovial inflammation detected ultrasonagraphically in hand joints.

Abstract
Aromatase inhibitors (AIs) are a standard of care for the adjuvant treatment of hormone responsive early carcinoma of the breast as demonstrated in a number of large international phase III randomised trials. Arthralgia was a somewhat unexpected side effect of this class of agents and has proven to be potentially problematic in clinical practice. Although rates of up 35% have been reported in the randomised trials, the figure has been much higher in subsequent case series. There is concern that these symptoms are significant and may affect compliance and thus the overall efficacy of treatment. It is therefore extremely important that we evaluate this syndrome with a view to gaining more information regarding its clinical features and possible aetiological mechanism. The potential aetiological mechanisms and evidence for aromatase inhibitor-induced arthralgia (AIA) are reviewed in this article. Looking forward, it is now important that prospective clinical trials are well designed to evaluate this syndrome and potential therapeutic strategies to circumvent it. Radiological imaging and biochemical analyses may help our understanding of AIA and these are discussed.

Abstract
BACKGROUND Ultrasonography has been increasingly utilised to aid the understanding and management of rheumatic conditions. In recent years there has been a focus on the validity and utility of ultrasonography in demonstrating joint pathology, although this has largely focused on inflammatory arthritis. AIMS To undertake a systematic review of the published literature evaluating ultrasonography as an assessment tool in osteoarthritis. METHODS Medline and Pubmed were searched to identify original manuscripts, published before June 2008, utilising ultrasonography to assess the joints of cohorts of subjects with osteoarthritis. Data were extracted from manuscripts meeting the inclusion criteria, with a particular focus on the pathology imaged, the definitions used, scoring systems and their metric properties. RESULTS Forty-seven studies were identified that utilised ultrasonography to assess structural pathology in osteoarthritis. Doppler function was only assessed in 10 studies and contrast agents in one. There was heterogeneity with regard to the pathology examined, the definition of pathology, quantification and the reporting of these factors. There was also a lack of construct and criterion validity and data demonstrating reliability and sensitivity to change. CONCLUSIONS Whereas there is increasing evidence of the validity of ultrasonography in detecting structural pathology in inflammatory arthritis, more work is required to develop standardised definitions of pathology and to demonstrate the validity of ultrasonography in osteoarthritis.

Abstract
OBJECTIVE RA has a substantial impact on both patients and healthcare systems. Our objective is to advance the understanding of modern management principles in light of recent evidence concerning the condition's diagnosis and treatment. METHODS A group of practicing UK rheumatologists formulated contemporary management principles and clinical practice recommendations concerning both diagnosis and treatment. Areas of clinical uncertainty were documented, leading to research recommendations. RESULTS A fundamental concept governing treatment of RA is minimization of cumulative inflammation, referred to as the inflammation-time area under the curve (AUC). To achieve this, four core principles of management were identified: (i) detect and refer patients early, even if the diagnosis is uncertain: patients should be referred at the first suspicion of persistent inflammatory polyarthritis and rheumatology departments should provide rapid access to a diagnostic and prognostic service; (ii) treat RA immediately: optimizing outcomes with conventional DMARDs and biologics requires that effective treatment be started early-ideally within 3 months of symptom onset; (iii) tight control of inflammation in RA improves outcome: frequent assessments and an objective protocol should be used to make treatment changes that maintain low-disease activity/remission at an agreed target; (iv) consider the risk-benefit ratio and tailor treatment to each patient: differing patient, disease and drug characteristics require long-term monitoring of risks and benefits with adaptations of treatments to suit individual circumstances. CONCLUSION These principles focus on effective control of the inflammatory process in RA, but optimal uptake may require changes in service provision to accommodate appropriate care pathways.

Abstract
Objectives:The aim of this study was to assess the value of power Doppler ultrasound (PDUS) in combination with routine management in a cohort of patients with very early inflammatory arthritis (IA).Methods:50 patients with ⩽12 weeks of inflammatory symptoms with or without signs had clinical, laboratory and imaging assessments. Diagnosis was recorded at 12 months. Assuming a 15% pre-test probability of IA, post-test probabilities for various assessments were calculated and used to develop a diagnostic algorithm.Results:All patients positive for rheumatoid factor (RF) and/or cyclic citrullinated peptide (CCP) developed persistent IA, so the added value of PDUS was assessed in the seronegative (RF and CCP negative) group. The probability of IA in a seronegative patient was 6%. The addition of clinical and radiographic features raised the probability of IA to 30% and, with certain ultrasound features, this rose to 94%.Conclusions:In seronegative patients with early IA, combining PDUS with routine assessment can have a major impact on the certainty of diagnosis.

Abstract
OBJECTIVE Few studies have examined hand osteoarthritis (OA) pathology using sensitive imaging techniques. The aim of this study was to determine the extent of ultrasound (US)-detected pathology and investigate its relationship with symptoms in hand OA. METHODS Subjects with symptomatic hand OA and controls were recruited. All underwent clinical and US examination of the small joints of both hands and completed a range of measures of hand pain, stiffness, and function. RESULTS Thirty-six subjects with symptomatic OA and 19 control subjects with similar demographics were recruited. US-detected pathology (osteophytes, joint space narrowing, gray-scale synovitis, and power Doppler signal) occurred frequently in symptomatic hand OA (41%, 40%, 46%, and 7% of joints, respectively), and significantly less often in controls (P < 0.001 for all comparisons). Symptomatic joints were more likely to demonstrate US-detected changes of gray-scale synovitis, power Doppler signal, or osteophytes (P < 0.001, P = 0.002, and P < 0.001, respectively). Neither the number of affected joints per individual nor the summative semiquantitative scores for synovitis per individual correlated with symptoms (pain visual analog scale [VAS], global VAS, or Australian/Canadian Osteoarthritis Hand Index). CONCLUSION This study demonstrated extensive synovitis changes as well as the traditional structural radiographic findings of hand OA. Symptomatic joints were significantly more likely to demonstrate US-detected structural changes or inflammation in symptomatic hand OA; however, the extent of changes in individual joints or in individuals did not correlate with the degree of symptoms, which may relate to both the assessment tools and the complex nature of pain.

Abstract
Objective:To assess the intra and interobserver reproducibility of musculoskeletal ultrasonography (US) among rheumatologists in detecting destructive and inflammatory shoulder abnormalities in patients with rheumatoid arthritis (RA) and to determine the overall agreement between US and MRI.Methods:A total of 14 observers examined 5 patients in 2 rounds independently and blindly of each other. US results were compared with MRI. Overall agreement of all findings, of positive findings on MRI, as well as intra and interobserver reliabilities, were calculated.Results:Overall agreement between US and MRI was seen in 79% with regard to humeral head erosions (HHE), in 64% with regard to posterior recess synovitis (PRS), in 31% with regard to axillary recess synovitis (ARS), in 64% with regard to bursitis, in 50% with regard to biceps tenosynovitis (BT), and in 84% for complete cuff tear (CCT). Intraobserver and interobserver κ was 0.69 and 0.43 for HHE, 0.29 and 0.49 for PRS, 0.57 and 1.00 for ARS, −0.17 and 0.51 for bursitis, 0.17 and 0.46 for BT and 0.52 and 0.6 for CCT, respectively. The intraobserver and interobserver κ for power Doppler (PD) was 0.90 and 0.70 for glenohumeral signals and 0.60 and 0.51 for bursal signals, respectively.Conclusions:US is a reliable imaging technique for most shoulder pathology in RA especially with regard to PD. Standardisation of scanning technique and definitions of particular lesions may further enhance the reliability of US investigation of the shoulder.

Abstract
OBJECTIVES The aim of this pilot study was to compare clinical examination (CE) and ultrasound (US) with high field MRI (as the reference standard) for the detection of rearfoot and midtarsal joint synovitis and secondly tenosynovitis of the ankle tendons in patients with established rheumatoid arthritis (RA). METHODS Patients with RA (as determined by the modified American College of Rheumatology (ACR) criteria) with symptoms of midfoot and rearfoot disease were recruited. Demographic data were collected. All underwent CE, US and high field MRI (with intravenous gadolinium contrast) of their right foot. Percentage exact agreement (PEA), sensitivity and specificity were calculated for CE and US when compared to MRI. Inter-reader reliability for CE and US was also assessed. RESULTS Compared to the gold standard of MRI, for CE (joint synovitis) the ranges for sensitivity, specificity and PEA were 55-83%, 23-46% and 46-60%, and for US were 64-89%, 60-80% and 64-78%, respectively. Compared to the gold standard of MRI, for CE (tenosynovitis) the ranges for sensitivity, specificity and PEA were 0-100%, 20-91% and 55-91%, and for US were 0-67%, 86-100% and 59-86%, respectively. CONCLUSION CE was sensitive but US more specific in identifying hindfoot pathology in RA when compared to the reference standard of MRI. There was poor interobserver variability between ultrasonographers suggesting a need for standardisation of acquisition and interpretation of US images of the hindfoot.

Abstract
OBJECTIVES Ultrasonography (US) is used in rheumatology to assess small joints in inflammatory arthritis. Recently there has been some investigation into the utility of US in osteoarthritis (OA), however there has been little comparison of US to other imaging modalities in OA. This study aimed to compare the detection of osteophytosis and joint space narrowing (JSN) by US and conventional radiography (CR) in OA of the hand. METHODS SUBJECTS with OA of the hand underwent US and CR examination of the small joints of both hands to identify osteophytosis and joint space narrowing. RESULTS 1106 joints of 37 patients were imaged with US and CR. US detected osteophytosis in 448 joints, compared to CR that detected osteophytosis in 228 joints (approximately 30% fewer joints). Where osteophytosis was detected by US but not CR, this was usually proximal to the joint line. Joint space narrowing was detected in 450 joints by US, but only 261 joints by CR. The distribution of US and CR detected osteoarthritis changes in this cohort was consistent with population studies of radiographic hand OA, although metacarpophalangeal (MCP) involvement was higher than might be expected CONCLUSIONS US detected more osteophytosis and joint space narrowing than CR in OA of the hand. Involvement of MCP joints was more common than would be expected from population radiographic studies. The increased detection of OA structural pathology by US may make this a useful tool for hand OA research.

Abstract
OBJECTIVE To develop education guidelines for the conduct of future European League Against Rheumatism (EULAR) musculoskeletal ultrasound (MSUS) courses. METHODS We undertook a consensus-based, iterative process using two consecutive questionnaires sent to 29 senior ultrasonographer rheumatologists who comprised the faculty of the 14th EULAR ultrasound course (June 2007). The first questionnaire encompassed the following issues: type of MSUS educational model; course timing; course curriculum; course duration; number of participants per teacher in practical sessions; time spent on hands-on sessions; and the requirements and/or restrictions for attendance at the courses. The second questionnaire consisted of questions related to areas where consensus had not been achieved in the first questionnaire, and to the topics and pathologies to be assigned to different educational levels. RESULTS The response rate was 82.7% from the first questionnaire and 87.5% from the second questionnaire. The respondents were from 11 European countries. The group consensus on guidelines and curriculum was for a three-level education model (basic, intermediate and advanced) with timing and location related to the annual EULAR Congresses. The topics and pathologies to be included in each course were agreed. The course duration will be 20 h. There will be a maximum of six participants per teacher and 50-60% of total time will be spent on practical sessions. There was also agreement on prerequisite experience before attending the intermediate and advanced courses. CONCLUSION We have developed European agreed guidelines for the content and conduct of EULAR ultrasound courses, which may also be recommended to national and local MSUS training programmes.

Abstract
OBJECTIVES Painful osteoarthritis (OA) of the hand is common and a validated ultrasound (US) scoring system would be valuable for epidemiological and therapeutic outcome studies. US is increasingly used to assess peripheral joints, though most of the US focus in rheumatic diseases has been on rheumatoid arthritis. We aimed to develop a preliminary US hand OA scoring system, initially focusing on relevant pathological features with potentially high reliability. METHODS A group of experts in the fields of OA, US and novel tool development agreed on domains and suggested scaling of the items to be used in US hand OA scoring systems. A multi-observer reliability exercise was then performed to evaluate the draft items. RESULTS Synovitis (grey scale and Power Doppler) and osteophytes (representing activity and damage domains) were included and evaluated as the initial components of the scoring system. All three features were evaluated for their presence/absence and if present were scored using a 1-3 scale. The reliability exercise demonstrated intra-reader kappa values of 0.444-1.0, 0.211-1.0 and 0.087-1.0 for grey scale synovitis, power Doppler and osteophytes respectively. Inter-reader reliability kappa values were 0.398, 0.327 and 0.530 grey-scale synovitis, power Doppler and osteophytes respectively. Without extensive standardisation, both intra- and inter-reader reliability were moderately good. CONCLUSIONS The draft scoring system demonstrated substantive to almost perfect percentage exact agreement on the presence/absence of the selected OA features and moderate to substantive percentage exact agreement on semi-quantitative grading. This preliminary process provides a good basis from which to further develop an US outcome tool for hand OA that has the potential to be utilised in multicentre clinical trials.

Abstract
This report presents the results of a recent systematic review performed by the OMERACT Ultrasound Group on the metric properties of ultrasound for the detection of synovitis in inflammatory arthritis. Reviews were conducted for the hand, wrist, elbow, shoulder, knee, ankle, and foot; most reports were related to the hand and knee, and the most common disease process was rheumatoid arthritis. The review highlights the current gaps in the literature, including a lack of reliability data with respect to intra-occasion and intra- and inter-reader reliability. Current work by our group is addressing these issues.

Abstract
Ultrasound (US) is a relatively new imaging modality in rheumatology that offers great potential as a diagnostic and management tool. In 2004, an OMERACT Ultrasound Special Interest Group was formed to address the metric qualities of US as a potential outcome measure. A preliminary systematic review highlighted the deficiencies in the literature, particularly with regard to the reliability of interpreting and acquiring images; as a consequence, a number of exercises were proposed to address these issues. This report describes a series of iterative studies that have resulted in improved intra- and inter-reader reliability for detecting and scoring synovitis from both static and real-time images of the hand joints of patients with rheumatoid arthritis. The reliability of acquiring images was also enhanced using standardized positions. Future studies will assess the value of US in clinical trials.

Abstract
OBJECTIVES Musculoskeletal ultrasonography (MSKUS) has been described by some rheumatologists as the 'stethoscope of the joint'. Such enthusiasm is supported by evidence confirming validity and clinical utility in evaluation of musculoskeletal diseases. But if rheumatologist-performed MSKUS is to emulate the impact of cardiologist-performed echocardiography, a number of educational challenges need be addressed. Evaluation of current training reveals the absence of a unified educational structure, ad hoc teaching and assessment and published data are insufficient to make practice and training recommendations specific to rheumatology. METHODS Informed by developments in adult-learning theory, we have utilized a competency-based approach to develop an educational programme for rheumatologist ultrasonographers. Fundamental to this process has been accurate functional analysis of the role of the rheumatologist ultrasonographer and precise translation of these data into educational outcomes. This involved a thorough, transparent, iterative, curriculum-defining approach, employing quantitative and qualitative research techniques including interview, questionnaire, Delphi and standard setting methodologies. All relevant stakeholders were engaged, including international US experts and clinical rheumatologists. RESULTS Outcomes include clarification of the role of a rheumatologist ultrasonographer; definition of appropriate knowledge and skills; establishment of competency standards; a balanced, clearly defined, clinically relevant educational outcome blueprint. Teaching and assessment approaches have been piloted as part of an accessible modular curriculum strategy. Thorough validation and evaluation confirms effectiveness, efficiency and suitability. CONCLUSIONS A comprehensive evidence-based, expert consensus-defined educational framework is proposed that provides a template for teaching and learning and standards for competency assessment. This should facilitate common principles of training, uniform professional practice and a justifiable governance structure.

Abstract
OBJECTIVES The practice of musculoskeletal ultrasonography (MSKUS) by UK rheumatologists remains limited, despite their reported enthusiasm. This study aimed to investigate factors that may encourage or limit future dissemination of rheumatologist-performed MSKUS and provide insights into perceived clinical importance and learning motivation relating to published recommendations by MSKUS experts. METHODS A written questionnaire study was conducted, involving 48 rheumatologists. Questions included the potential role of self-performed MSKUS, skills that they would be willing to learn and factors that may encourage or limit learning and practice. Competency recommendations proposed by imaging experts (142 skills in 7 anatomical areas) were reviewed, and quantitative and qualitative data collected regarding 'value to their practice' and 'learning motivation'. RESULTS Eighty-nine percent wished to learn MSKUS. Factors influencing learning and practice included time to achieve competency; relative-added clinical value of MSKUS examination; limited training infrastructure; access to existing imaging service; equipment funding. Skills offering greatest clinical utility were inflammatory arthritis assessment and guided procedures; least useful were evaluation of ligament/muscle lesions and soft tissue masses. There was a close correlation between clinical utility, learning motivation and competency standard. CONCLUSIONS A trade-off between added clinical value and time to achieve competency is the major factor influencing practice and training in MSKUS. Most rheumatologists report limited time to devote to training and therefore need to prioritize areas of importance for dedicated learning. Educational programmes need to be highly focused and relevant to clinical and job-plan requirements in order to encourage future dissemination of MSKUS practice by rheumatologists.

Abstract
OBJECTIVE To investigate the frequency and distribution of finger tenosynovitis in patients with early, untreated rheumatoid arthritis (RA) using gray-scale ultrasound (US) and magnetic resonance imaging (MRI). METHODS Fifty patients underwent US and MRI of metacarpophalangeal (MCP) joints 2-5. Twenty healthy controls underwent US only. Flexor and extensor involvement was documented for each joint. Intrareader reliability (IRR) was calculated by rereading static images. RESULTS Flexor tenosynovitis was found in 57 (28.5%) of 200 joints in 24 (48%) of 50 patients on US compared with 128 (64%) of 200 joints in 41 (82%) of 50 patients on MRI. Periextensor tenosynovitis was found in 14 (7%) joints in 9 (18%) patients on US compared with 80 (40%) joints in 36 (72%) patients on MRI. No controls had imaging tenosynovitis. Using MRI as the gold standard, the sensitivity, specificity, and negative and positive predictive values for US were 0.44, 0.99, 0.49, and 0.98, respectively, for flexor tenosynovitis and 0.15, 0.98, 0.63, and 0.86 for extensor tenosynovitis, respectively. The IRR was 0.85 and 0.8 for US and MRI, respectively. The most frequently involved joints on US and MRI were the second and third MCP joints. CONCLUSION This is the first study to compare US and MRI for the detection of tenosynovitis in the fingers of patients with early untreated RA. Tenosynovitis was found to be common using both modalities, with MRI being more sensitive. A negative US scan does not exclude inflammation and an MRI should be considered. Further work is recommended to standardize definitions and image acquisition for both US and MRI images.

METHODS Patients with <or=4 joints with clinical synovitis (disease duration <or=12 months) were randomized to early intervention (EI) with intraarticular methylprednisolone into all synovitic joints or to conservative treatment (CT) with nonsteroidal antiinflammatory drugs alone. Sulfasalazine was administered in both groups for persistent disease or disease that evolved into a polyarthritis. Primary outcome was complete response (CR) defined as the absence of synovitis at 52 weeks. Secondary outcomes included CR at weeks 4 and 12, function (Health Assessment Questionnaire), pain (0-100-mm visual analog scale), and work status. RESULTS Fifty-nine patients (34 men, 25 women; mean age 32.9 years; median early morning stiffness 30 minutes) were randomized. At baseline, two-thirds reported that they were work impaired. At 52 weeks, 81% of patients in the EI group achieved CR compared with 57% in the CT group (chi(2) = 3.833, 1 df, P = 0.05). In addition, 45% of patients in the EI group received sulfasalazine as opposed to 14% in the CT group (chi(2) = 5.156, 1 df, P = 0.019). There were no differences in physical disability or work impairment between the treatment groups. CONCLUSION Oligoarthritis has a significant impact on function and work ability. Patients treated with EI using intraarticular corticosteroids followed by sulfasalazine therapy if resistant demonstrated reduced synovitis 12 months after treatment compared with those initially treated with more conservative therapy.

Abstract
BACKGROUND Hand pain with stiffness is a common clinical presentation to early arthritis clinics, with outcome varying from resolution to the development of rheumatoid arthritis. OBJECTIVE To assess the response and predictors of response to intramuscular methylprednisolone (MP) and hydroxychloroquine (HCQ) using a standardised treatment protocol. METHODS Patients with inflammatory hand pain (IHP), defined as predominantly hand pain and morning stiffness of at least 30 min duration, received a standardised assessment prior to receiving intramuscular MP. Response (primary outcome) at 4 weeks was a 50% improvement in symptoms as perceived by the patient; responders who relapsed received repeat intramuscular MP and HCQ. RESULTS 102 patients were recruited, of which 21% were rheumatoid factor (RF) positive, 23% had clinical synovitis, 25% had raised C-reactive protein level and 55% had ultrasound-detected synovitis. 73% responded, with associated significant reductions in morning stiffness, Health Assessment Questionnaire, painful and tender joint counts, and visual analogue scores (p < or = 0.006 for all). Ultrasound-detected synovitis (p<0.001) and RF (p = 0.04), but not clinical synovitis (p = 0.74), were significantly associated with response to intramuscular MP. 86% who remained on HCQ long term reported a benefit. CONCLUSIONS Patients with IHP have significant improvement in symptoms and function following intramuscular MP. Further placebo-controlled trials are required to assess the role of intramuscular MP and ultrasonography in managing this patient group.

Abstract
BACKGROUND A competency based approach to the education of rheumatologists in musculoskeletal ultrasonography (MSK US) ensures standards are documented, transparent, accountable, and defensible, with clear benefit to all stakeholders. Specific competency outcomes will facilitate informed development of a common curriculum and structured programme of training and assessment. OBJECTIVE To determine explicit competency based learning outcomes for rheumatologists undertaking MSK US. METHODS International experts in MSK US, satisfying specific selection criteria, were asked to define the minimum standards required by a rheumatologist to be judged competent in MSK US. They reviewed 115 MSK US skills, comprising bone and soft tissue pathology, in seven joints regions of the upper and lower limbs, and rated their relative importance according to specific criteria. These data are presented as specific educational outcomes within designated competency categories. RESULTS 57 expert MSK US practitioners were identified and 35 took part in this study. Ten generic core competency outcomes were recognised including physics, anatomy, technique, and interpretation. Regarding specific regional competencies, 53% (61/115) were considered "must know" core learning outcomes, largely comprising inflammatory joint/tendon/bone pathology and guided procedures; 45% (52/115) were required at an intermediate/advanced level (18/115 "should know", 34/115 "could know"), and 2% (2/115) were deemed inappropriate/unnecessary for rheumatologist ultrasonographers. CONCLUSIONS This is the first study to developing a competency model for the education of rheumatologists in MSK US based on the evidence of international experts. A specific set of learning outcomes has been defined, which will facilitate future informed education and practice development and provide a blueprint for a structured rheumatology MSK US curriculum and assessment process.

Abstract
Rheumatoid arthritis (RA) is a chronic and progressive inflammatory disorder primarily affecting the synovium and is characterized by destruction of bone and cartilage. Early diagnosis and treatment of RA can improve disease outcomes substantially. Magnetic resonance imaging and musculoskeletal ultrasonography may facilitate early diagnosis and aid the targeting of intensive therapy. Magnetic resonance imaging and musculoskeletal ultrasonography also are able to monitor temporal changes in disease activity (ie, synovitis) and damage (ie, erosions). These imaging modalities are likely to be increasingly used in the management of early rheumatoid arthritis to ensure the best patient outcomes, although more work is required to determine their optimal roles.

Abstract
OBJECTIVE More timely and effective therapy for rheumatoid arthritis (RA) has contributed to increasing rates of clinical remission. However, progression of structural damage may still occur in patients who have satisfied remission criteria, which suggests that there is ongoing disease activity. This questions the validity of current methods of assessing remission in RA. The purpose of this study was to test the hypothesis that modern joint imaging improves the accuracy of remission measurement in RA. METHODS We studied 107 RA patients receiving disease-modifying antirheumatic drug therapy who were judged by their consultant rheumatologist to be in remission and 17 normal control subjects. Patients underwent clinical, laboratory, functional, and quality of life assessments. The Disease Activity Score 28-joint assessment and the American College of Rheumatology remission criteria, together with strict clinical definitions of remission, were applied. Imaging of the hands and wrists using standardized acquisition and scoring techniques with conventional 1.5T magnetic resonance imaging (MRI) and ultrasonography (US) were performed. RESULTS Irrespective of which clinical criteria were applied to determine remission, the majority of patients continued to have evidence of active inflammation, as shown by findings on the imaging assessments. Even in asymptomatic patients with clinically normal joints, MRI showed that 96% had synovitis and 46% had bone marrow edema, and US showed that 73% had gray-scale synovial hypertrophy and 43% had increased power Doppler signal. Only mild synovial thickening was seen in 3 of the control subjects (18%), but no bone marrow edema. CONCLUSION Most RA patients who satisfied the remission criteria with normal findings on clinical and laboratory studies had imaging-detected synovitis. This subclinical inflammation may explain the observed discrepancy between disease activity and outcome in RA. Imaging assessment may be necessary for the accurate evaluation of disease status and, in particular, for the definition of true remission.

Abstract
Ultrasound (US) has great potential as an outcome in rheumatoid arthritis trials for detecting bone erosions, synovitis, tendon disease, and enthesopathy. It has a number of distinct advantages over magnetic resonance imaging, including good patient tolerability and ability to scan multiple joints in a short period of time. However, there are scarce data regarding its validity, reproducibility, and responsiveness to change, making interpretation and comparison of studies difficult. In particular, there are limited data describing standardized scanning methodology and standardized definitions of US pathologies. This article presents the first report from the OMERACT ultrasound special interest group, which has compared US against the criteria of the OMERACT filter. Also proposed for the first time are consensus US definitions for common pathological lesions seen in patients with inflammatory arthritis.

Abstract
OBJECTIVES (1) To examine the change in regional bone mineral density (BMD), including the hands, and assess its role as a predictor of outcome in patients presenting with an early undifferentiated inflammatory arthritis; (2) to examine for associations with the changes in hand BMD. METHODS 74 patients with undifferentiated hand arthritis of less than 12 months' duration were examined at baseline and then at three, six, and 12 months follow up, including BMD measurement of the femoral neck, spine (L2-4), and the whole hands using dual energy absorptiometry (DXA). RESULTS During the study, 13 patients were diagnosed as having rheumatoid arthritis, 19 as having inflammatory non-rheumatoid joint disorders, and 42 as having non-inflammatory joint disorders. At the femoral neck and lumbar spine no significant bone loss was seen in any of the three subgroups. At the 12 months follow up the mean (95% confidence interval) hand BMD loss in the patients with rheumatoid arthritis was -4.27% (-1.41 to -7.13); in the inflammatory non-rheumatoid group, -0.49% (-1.33 to +0.35); and in the non-inflammatory joint disorder group, -0.87% (-1.51 to -0.23). In a multivariate linear regression model (including age, rheumatoid factor, mean C reactive protein, mean HAQ score, and cumulative glucocorticoid dose), only mean C reactive protein (p<0.001) and rheumatoid factor (p = 0.04) were independently associated with change in hand BMD during follow up. CONCLUSIONS Hand DXA provides a very sensitive tool for measuring bone loss in early rheumatoid arthritis and may be useful in identifying patients at high risk of developing progressive disease. Further studies are needed to evaluate the role of hand bone loss as a prognostic factor and outcome measure in rheumatoid arthritis.

Abstract
OBJECTIVE To assess the interobserver reliability of the main periarticular and intra-articular ultrasonographic pathologies and to establish the principal disagreements on scanning technique and diagnostic criteria between a group of experts in musculoskeletal ultrasonography. METHODS The shoulder, wrist/hand, ankle/foot, or knee of 24 patients with rheumatic diseases were evaluated by 23 musculoskeletal ultrasound experts from different European countries randomly assigned to six groups. The participants did not reach consensus on scanning method or diagnostic criteria before the investigation. They were unaware of the patients' clinical and imaging data. The experts from each group undertook a blinded ultrasound examination of the four anatomical regions. The ultrasound investigation included the presence/absence of joint effusion/synovitis, bony cortex abnormalities, tenosynovitis, tendon lesions, bursitis, and power Doppler signal. Afterwards they compared the ultrasound findings and re-examined the patients together while discussing their results. RESULTS Overall agreements were 91% for joint effusion/synovitis and tendon lesions, 87% for cortical abnormalities, 84% for tenosynovitis, 83.5% for bursitis, and 83% for power Doppler signal; kappa values were good for the wrist/hand and knee (0.61 and 0.60) and fair for the shoulder and ankle/foot (0.50 and 0.54). The principal differences in scanning method and diagnostic criteria between experts were related to dynamic examination, definition of tendon lesions, and pathological v physiological fluid within joints, tendon sheaths, and bursae. CONCLUSIONS Musculoskeletal ultrasound has a moderate to good interobserver reliability. Further consensus on standardisation of scanning technique and diagnostic criteria is necessary to improve musculoskeletal ultrasonography reproducibility.

Abstract
OBJECTIVE To evaluate the interobserver reliability among 14 experts in musculoskeletal ultrasonography (US) and to determine the overall agreement about the US results compared with magnetic resonance imaging (MRI), which served as the imaging "gold standard". METHODS The clinically dominant joint regions (shoulder, knee, ankle/toe, wrist/finger) of four patients with inflammatory rheumatic diseases were ultrasonographically examined by 14 experts. US results were compared with MRI. Overall agreements, sensitivities, specificities, and interobserver reliabilities were assessed. RESULTS Taking an agreement in US examination of 10 out of 14 experts into account, the overall kappa for all examined joints was 0.76. Calculations for each joint region showed high kappa values for the knee (1), moderate values for the shoulder (0.76) and hand/finger (0.59), and low agreement for ankle/toe joints (0.28). kappa Values for bone lesions, bursitis, and tendon tears were high (kappa = 1). Relatively good agreement for most US findings, compared with MRI, was found for the shoulder (overall agreement 81%, sensitivity 76%, specificity 89%) and knee joint (overall agreement 88%, sensitivity 91%, specificity 88%). Sensitivities were lower for wrist/finger (overall agreement 73%, sensitivity 66%, specificity 88%) and ankle/toe joints (overall agreement 82%, sensitivity 61%, specificity 92%). CONCLUSION Interobserver reliabilities, sensitivities, and specificities in comparison with MRI were moderate to good. Further standardisation of US scanning techniques and definitions of different pathological US lesions are necessary to increase the interobserver agreement in musculoskeletal US.

Abstract
OBJECTIVE To evaluate the training and practice of specialist practitioners in musculoskeletal ultrasonography (MUS) with the aim of developing an expert-derived consensus of educational standards for rheumatologists performing MUS. METHODS A panel of worldwide experts in MUS was identified by literature review, consultation with members of training committees, and peer recommendation. Using a postal questionnaire, information was obtained about personal experience, current practice, training regimen, and participation in competency assessment. RESULTS International experts in MUS were identified (57 in total: 37 radiologists, 20 rheumatologists). Response rate was 70%. Radiologists had been performing MUS for longer than rheumatologists. Both rheumatologists and radiologists conducted the same number of MUS sessions per week, although radiologists examined more patients. More radiologists performed MUS for muscle and ligament injury, nerve lesions, soft tissue masses, and of the groin (P <0.01). The number of training hours was similar. Approaches to training varied, although attending a training course and scanning with an expert was more common among rheumatologists (P <0.001). More than two-thirds of the group had not undergone any form of competency assessment. CONCLUSION This study highlights differences in training and practice between individual expert ultrasonographers and between specialty backgrounds. In particular, there appears to be no formal training regimen and competency assessment is uncommon. The establishment of a core set of internationally applicable educational standards for MUS training for rheumatologists is required.

Abstract
OBJECTIVE To establish an expert consensus of best practice for rheumatologists performing musculoskeletal ultrasonography (MUS). METHODS A panel of worldwide experts in MUS was identified by literature review, membership of teaching faculty, and peer recommendation. They were invited to take part in a 4-stage Delphi process employing 2 iterative rounds to establish a consensus of specific indications, anatomic areas, and knowledge and skills required by rheumatologists performing MUS. RESULTS Experts in MUS were identified (n = 57; 37 radiologists, 20 rheumatologists). Successive rounds of this rigorous Delphi exercise enabled group consensus to be achieved in 30 of the proposed 37 categories comprising 8 of 13 indications (inflammatory arthritis, tendon pathology, effusion, bursitis, monitoring disease activity, monitoring disease progression, guided aspiration, and injection), 8 of 10 anatomic areas (hand, wrist, elbow, shoulder, hip, knee, ankle and heel, and forefoot), and 14 categories of knowledge and skills (physics, anatomy, pathology, equipment, clinical application and relevance, indications and limitations, artifact, machine function and operation, patient and probe position, planes and system of examination, image optimization, dynamic assessment, color Doppler, and power Doppler). CONCLUSION We have produced the first expert-derived, interdisciplinary consensus of recommendations for rheumatologists performing MUS. This represents a significant advance that will not only direct future rheumatology MUS practice, but will facilitate informed educational development. This is an important step towards the introduction of a specific training curriculum and assessment process to ensure competent rheumatologist ultrasonographers.

Abstract
Imaging techniques such as musculoskeletal ultrasonography (MUS) and magnetic resonance imaging (MRI) are playing an increasingly important role in the assessment of patients with inflammatory arthritis. Such modalities are now used routinely in the evaluation of joint, tendon and soft tissue inflammation and bone damage in many early arthritis clinics. They have the ability to directly visualise, characterise and quantify the earliest inflammatory changes and have proved not only to be useful additional complimentary clinical tools to improve the speed and accuracy of diagnosis, direct appropriate treatment, monitor response to therapy, measure disease progression and outcome but also continue to contribute to our understanding of disease pathogenesis. These imaging methods may therefore offer a significant advantage as they endorse the principles of early diagnosis and optimal targeted therapy essential to providing the most favourable long term outcome for patients with inflammatory arthritis. This article reviews the current evidence supporting the role of MUS and MRI in the assessment of patients with inflammatory arthritis.

Abstract
New imaging techniques such as ultrasound and MRI are likely to play increasing roles in the future management of patients with inflammatory arthritis, particularly those with rheumatoid arthritis and spondyloarthropathies. Ultrasound has a number of distinct advantages including its ability to scan multiple joints, safety, and immediately availability in clinic. MRI, however, is more sensitive and has a greater field of view because of its tomographic nature. Both modalities have the added advantage over radiography in that they can image soft tissue as well as bone. Dual X-ray absorptiometry already has an established role to play in the assessment of osteoporosis, but new techniques such as digital radiogrametry, quantitative CT, and ultrasound potentially will have a more important role to play in the future.
