Abstract
OBJECTIVE To evaluate the metric qualities of power Doppler ultrasound (PDUS) for different quantification methods and devices in the assessment of arthritis during anti-inflammatory treatment. METHODS Twenty-four patients with active arthritis and first-time treatment with the TNF-alpha inhibitor adalimumab underwent sequential clinical, laboratory and US examination at baseline, weeks 2, 6 and 12. 2D and 3D PDUS was performed by two independent investigators. The images and movies were scored from 0 to 3 and the amount of colour pixels and voxels was calculated. In addition, the resistance index of a synovial artery was measured. Thirteen patients were examined with a second US machine. RESULTS Treatment response was already observed at week 2 with a significant reduction of 2D (P < 0.01) and 3D scores (P < 0.001). A moderate correlation to 28-joint disease activity score was found for 3D voxel count (r(s) = 0.35, P < 0.001). Interobserver agreement was kappa or ICC >or= 0.8 for all methods except the resistance index (ICC = 0.60). Intermachine agreement was kappa = 0.57 for 2D PDUS score. CONCLUSIONS The study demonstrates good to excellent interobserver and moderate intermachine reliability of different PDUS assessment methods in a longitudinal open-label study.

Limits and perspectives of ultrasound in the diagnosis and management of rheumatic diseases. Mod Rheumatol 2008; 18:125-31.

Abstract
Musculoskeletal sonography (MSUS) has played a growing role in the diagnosis and management of rheumatic diseases, enabling the imaging of synovitis, bone erosion, and cartilage damage in the early phase of arthritis. "Dynamic" evaluation of tendons and help in guiding needle positioning in interventional manoeuvres are some of the other reasons for its success. MSUS, particularly when coupled with power Doppler (PD) examination, has recently been shown to be an efficient tool for monitoring disease activity and progression in rheumatoid arthritis, spondyloarthritis, crystal-related arthropathy, and osteoarthritis, with general consensus on its interesting results. More specifically, the PD signal has proved to be a simple and promising tool for short-term monitoring of synovial vascularity changes induced by steroids or biological agents in RA patients. MSUS has some limits, because of the physical properties of US and the quality of the equipment; it is, moreover, an operator-related imaging technique, with few standardized protocols. Future goals should be standardization of the examining approach in grey scale and Doppler ultrasound (US), including use of new equipment (3D US), extensive use in other fields (i.e. connective tissue diseases and vasculitis), and possible new applications (e.g. thoracic US).

Abstract
The aim of this article was to review the current status of ultrasound imaging of patients with rheumatological disorders of the hands and feet. Ultrasound machines with high-resolution surface probes are readily available in most radiology departments and can be used to address important clinical questions posed by the rheumatologist and sports and rehabilitation physician. There is increasing evidence that ultrasound detects synovitis that is silent to clinical examination. Detection and classification of synovitis and the early detection of bone erosions are important in clinical decision making. Ultrasound has many advantages over other imaging techniques with which it is compared, particularly magnetic resonance. The ability to carry out a rapid assessment of many widely spaced joints, coupled with clinical correlation, the ability to move and stress musculoskeletal structures and the use of ultrasound to guide therapy accurately are principal amongst these. The use of colour flow Doppler studies provides a measure of neovascularisation within the synovial lining of joints and tendons, and within tendons themselves, that is not available with other imaging techniques. Disadvantages compared to MRI include small field of view, poor image presentation, and difficulty in demonstrating cartilage and deep joints in their entirety. Contrast-enhanced magnetic resonance provides a better measure of capillary permeability and extracellular fluid than does ultrasound. The ability to image simultaneously multiple small joints in the hands and feet and their enhancement characteristics cannot be matched with ultrasound, though future developments in 3-D ultrasound may narrow this gap. Magnetic resonance provides a more uniform and reproducible image for long-term follow-up studies.

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
PURPOSE OF REVIEW An update of the latest developments in ultrasonography in rheumatology. Indications, technical aspects and representative examples of the potential of ultrasonography are illustrated. Finally, education and training issues are briefly discussed. RECENT FINDINGS Ultrasonography can be used in rheumatology for a wide spectrum of indications including inflammatory arthritis, tendon pathology, bursitis, disease activity monitoring, disease progression monitoring, guided aspiration and guided injections. Latest-generation ultrasonography systems provide a very sensitive assessment of both grayscale and Doppler findings. The quality of results in ultrasonography is conditioned by a series of elements that include the characteristics of the equipment, knowledge of relevant anatomy and pathology, experience of the sonographer, techniques used and patient positioning. SUMMARY Ultrasonography is challenging the standards of rheumatological clinical practice. It is more sensitive than clinical examination in the detection of synovitis and more sensitive than conventional radiography in the detection of bone erosions. Ultrasonography-guided injections may improve therapy effectiveness if compared with the traditional blind approach. Three-dimensional ultrasonography with a volumetric probe and the power Doppler mode may represent a very useful tool for therapy monitoring in patients with chronic arthritis.

Abstract
OBJECTIVE To evaluate the sensitivity to change of power Doppler ultrasound (PDUS) assessment of joint inflammation and the predictive value of PDUS parameters in disease activity and radiologic outcome in patients with early rheumatoid arthritis (RA). METHODS Forty-two patients with early RA who started therapy with disease-modifying antirheumatic drugs underwent blinded sequential clinical, laboratory, and ultrasound assessment at baseline, 3 months, 6 months, and 1 year and radiographic assessment at baseline and 1 year. For each patient, 28-joint Disease Activity Score (DAS28) was recorded at each visit. The presence of synovitis was investigated in 28 joints using gray-scale ultrasonography and intraarticular power Doppler signal. Active synovitis was defined as intraarticular synovitis detected with power Doppler signal. The ultrasound joint count for active synovitis and an overall joint index for power Doppler signal were calculated. Sensitivity to change of PDUS variables was assessed by estimating the smallest detectable difference (SDD) from the intraobserver variability. RESULTS The SDD for ultrasound joint count for active synovitis and ultrasound joint index for power Doppler signal was lower than mean changes from baseline to 3 months, 6 months, and 1 year. Time-integrated values of PDUS parameters demonstrated a highly significant correlation with DAS28 after 1 year (r = 0.63, P < 0.001) and a stronger correlation with radiographic progression (r = 0.59-0.66, P < 0.001) than clinical and laboratory parameters (r < 0.5). CONCLUSION PDUS is a sensitive and reliable method for longitudinal assessment of inflammatory activity in early RA. PDUS findings may have a predictive value in disease activity and radiographic outcome.

Abstract
OBJECTIVE To evaluate the performance characteristics of power Doppler ultrasound as a diagnostic and monitoring tool in the assessment of musculoskeletal disease through a systematic review of the literature. METHODS SEARCH STRATEGY We performed a literature search of PUBMED (1966 to June 2005). SELECTION CRITERIA Only original research reports written in English involving musculoskeletal disease and power Doppler ultrasound were included. Reviews were noted but not included. Data Extraction/Reporting: The design, subjects, methods, imaging protocols, and performance characteristics studied in the research papers were reported. RESULTS Of 3568 identified reports, 139 involved power Doppler ultrasound of the musculoskeletal system. Fifty-three of these reports met the inclusion criteria. Ultrasound machine settings were specified in 63% of reports. Rheumatoid arthritis was the most commonly studied musculoskeletal disease (64% of papers). Validity was the most studied performance characteristic (94% of reports), while reliability and responsiveness were studied in 17 and 34%, respectively. CONCLUSIONS Although the majority of research reports of power Doppler ultrasound assessment of the musculoskeletal system evaluated validity, less than half reported reliability and responsiveness. Further work is needed to evaluate power Doppler ultrasound assessment of the musculoskeletal system before it can be used to guide clinical decisions or be used as an endpoint in clinical trials.

Abstract
OBJECTIVE To assess the intra-reader and inter-reader reliabilities of interpreting ultrasonography by several experts using video clips. METHOD 99 video clips of healthy and rheumatic joints were recorded and delivered to 17 physician sonographers in two rounds. The intra-reader and inter-reader reliabilities of interpreting the ultrasound results were calculated using a dichotomous system (normal/abnormal) and a graded semiquantitative scoring system. RESULTS The video reading method worked well. 70% of the readers could classify at least 70% of the cases correctly as normal or abnormal. The distribution of readers answering correctly was wide. The most difficult joints to assess were the elbow, wrist, metacarpophalangeal (MCP) and knee joints. The intra-reader and inter-reader agreements on interpreting dynamic ultrasound images as normal or abnormal, as well as detecting and scoring a Doppler signal were moderate to good (kappa = 0.52-0.82). CONCLUSIONS Dynamic image assessment (video clips) can be used as an alternative method in ultrasonography reliability studies. The intra-reader and inter-reader reliabilities of ultrasonography in dynamic image reading are acceptable, but more definitions and training are needed to improve sonographic reproducibility.

Abstract
OBJECTIVE To use power Doppler sonography (PDS) to evaluate changes in synovial perfusion induced by adalimumab in the wrist joints of patients with rheumatoid arthritis. METHODS 48 wrists of 24 patients (18 women and 6 men) were examined. Despite prior treatment with disease-modifying antirheumatic drugs, including methotrexate, patients with clinically active rheumatoid arthritis were recruited in two rheumatological centres to receive 40 mg adalimumab subcutaneously every other week. Clinical, laboratory and PDS assessments were carried out at 0, 2, 6 and 12 weeks. Clinical and laboratory measurements of disease activity included physician's global assessment of disease activity, erythrocyte sedimentation rate and serum levels of C reactive protein. The Disease Activity Score for 28 joints (DAS28) was calculated. PDS signal was scored from 0 to 3 according to the overall expression of PDS findings at the wrists. RESULTS A significant reduction in both clinical (p<0.001) and PDS findings (p<0.001) was found at all follow-up examinations. A tendency to positive correlation (Spearman's r = 0.382; p = 0.067) was shown between reduction in PDS score and improvement in DAS28 at week 2 examination. CONCLUSION PDS detected a rapid and significant reduction in synovial perfusion at the wrist joints of patients with rheumatoid arthritis receiving adalimumab. Ongoing follow-up will provide further information regarding the persistence of considerable reduction in PDS signal score and its correlation with DAS28.

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
Over the last decade, several studies have highlighted the value of ultrasonography for both clinical and research purposes in rheumatology. Ultrasonography is a non-invasive, inexpensive and free-of-radiation-hazards imaging technique providing quick and useful information for the management of rheumatic diseases. Considerable evidence supporting the role of ultrasonography in rheumatological clinical practice has led many rheumatologists to want to become experienced with this imaging technique. The main indications of ultrasonography in rheumatology include the evaluation of patients with regional pain syndromes and chronic arthritis, short-term therapy monitoring and guidance for invasive procedures. Ultrasonography's long learning curve is the main obstacle that hinders its widespread use in rheumatology. Many technical aspects may affect the scanning process and a correct interpretation of sonographic images depends on several elements such as a deep knowledge of ultrasonography anatomy and pathology.

Abstract
PURPOSE OF REVIEW Rheumatoid arthritis is a chronic systemic and progressive inflammatory disorder of the synovium characterised by destruction of bone and cartilage. It is associated with significant morbidity and economic costs. Recent advances have shown that early diagnosis and timely, intensive therapy of rheumatoid arthritis can modify disease outcomes. RECENT FINDINGS Current investigations into the role of ultrasonography and magnetic resonance imaging in early rheumatoid arthritis suggest these modalities will provide information to assist in the early diagnosis of rheumatoid arthritis, identify poor prognostic factors, and aid in the monitoring of response to therapy. New developments in pharmacologic therapy, particularly the development of biologic agents, allow better disease control than was previously achievable, and the early application of these drugs in combination with conventional disease-modifying antirheumatic drugs seems to produce the best outcomes. SUMMARY The application of novel imaging techniques will aid the target application of biologic therapy within the window of opportunity and aid in the monitoring of response to therapy. This is likely to significantly decrease the rate of structural damage and offers hope of a future when the normal outcome for rheumatoid arthritis will be remission.

Abstract
Over the last few years a sonographic revolution has occurred in rheumatology. Ultrasonography has been shown to be capable of substantially changing the traditional approach to most clinical problems in daily rheumatological practice because of its ability to allow a quick, safe and inexpensive access to otherwise undetectable anatomical information on the early targets of most rheumatic diseases. Ultrasonography completes the physical examination in a rapid and accurate manner and allows the detection of a wide spectrum of pathological findings involving different anatomical structures in the musculoskeletal system. Guidance for intervention (joint aspiration, synovial or soft tissue biopsy, joint or tendon sheath injection) is a major application of ultrasonography. Sonographic guidance is particularly useful when fluid collections are very small or when the inflammatory process is adjacent to anatomical structures that could be seriously damaged by the injection.

Abstract
Vascular pathology, in the form of angiogenesis, is important in the perpetuation of rheumatoid arthritis (RA) and, in the form of endothelial dysfunction, contributes to associated cardiovascular co-morbidity. Emerging evidence suggests that TNFalpha blockade may modify vascular pathology in RA. Serum concentrations of vascular endothelial growth factor (VEGF), a potent endothelial cell-specific growth factor that is up-regulated by pro-inflammatory cytokines and by hypoxia, are elevated in RA and correlate with disease activity. Serum levels of VEGF at first presentation in RA predict radiographic progression of the disease over the subsequent year. Power Doppler ultrasonography is a sensitive method for demonstrating the presence of blood flow in small vessels and the vascular signal correlates with histopathological quantification of the vascular density of synovial tissue. Recent data indicate that high-frequency ultrasound and power Doppler are sensitive tools for evaluation of disease activity and assessment of response to therapy. Power Doppler imaging may also have the potential to predict those patients most at risk of accelerated joint destruction. However, much work has yet to be done to standardize the use of these imaging technologies.

Abstract
OBJECTIVE To determine the effect of tumour necrosis factor alpha (TNFalpha) blockade with etanercept in refractory knee joint synovitis (KJS) in rheumatoid and psoriatic arthritis, by local and systemic disease activity assessment and combined grey scale and power Doppler ultrasonographic monitoring. METHODS 27 knees affected by rheumatoid KJS (n = 12) and psoriatic KJS (n = 8) were assessed before receiving treatment and at 3 and 12 months' follow up. Time dependent clinical changes in disease activity were monitored by C reactive protein, erythrocyte sedimentation rate (ESR), global health status (GHS), and Ritchie (RAI) and knee joint articular (KJAI) indices; synovial changes were monitored by ultrasonographic and power Doppler indices for grey scale synovial thickening and for distinct intrasynovial vessel power Doppler flow configurations (fluid/synovium interface (F/SI-PD) and pannus/cartilage interface (P/CI-PD)). Interobserver and intraobserver variability of grey scale and power Doppler ultrasonographic was evaluated. Response to treatment was assessed by analysis of variance for repeated measures on clinical and ultrasonographic variables. RESULTS Rapid (3 months) reduction in F/SI-PD flow (p<0.001), parallel to reductions of C reactive protein (p<0.05), ESR (p<0.001), KJAI (p<0.002), RAI, and GHS (p<0.001), was sustained at 12 months when it was accompanied by reduction in both synovial thickening and P/CI-PD flow (p<0.001). No differences (ANOVA) were noted at baseline or at 12 months in clinical and ultrasonographic variables between either the rheumatoid or the psoriatic KJS groups. CONCLUSION Grey scale and power Doppler ultrasonography are reliable measures of long term change in rheumatoid and psoriatic KJS disease activity in response to anti-TNFalpha treatment with etanercept.
