Ultrasound Int Open 2018; 4:E61-E68. [PMID: 30182091 PMCID: PMC6120755 DOI: 10.1055/a-0612-7852] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2016] [Revised: 02/15/2018] [Accepted: 04/02/2018] [Indexed: 10/28/2022] Open
Abstract
Background The detection of joint swelling caused by synovitis is important for the diagnosis of inflammatory arthritis. Ultrasound (US) and MRI have proven to be more sensitive and reliable than physical examination, but they are time-consuming and expensive. The automated breast volume scanner was developed to acquire serial B-mode pictures of the female breast and these can be analyzed in all three dimensions. Objectives To analyze the value of automated B-mode ultrasound employing the ABVS system in detecting synovitis of the finger joints compared to manual ultrasound (mUS) and physical examination, using MRI as the gold standard. Methods 19 consecutive patients suffering from active rheumatoid (n=15) or psoriatic (n=4) arthritis were included. Automated and mUS were conducted with a linear array (ACUSON S2000™, 11 MHz). Multiplanar reconstruction enabled examination of the images for the presence of synovitis. Results 90% of the hand joints were assessable by automated ultrasound. Automated US detected 12.0, mUS 14.2, MRI 13.4, and clinical examination 4.1 positive joints - i. e. joints with synovitis - on average per patient. The inter-observer reliability of both assessors for automated and mUS, MRI, and physical examination, was 66.9%, 72.7%, 95.1%, and 88.9%, respectively. 84.3% of the joints classified as positive on MRI were confirmed by automated ultrasound, 85.5% on mUS, and 36.0 on physical examination. This translated into a sensitivity of 83.5%, 85.5%, and 36.0% for the three methods, respectively. Conclusion: Automated ultrasound is a promising ultrasound method for assessing small joints in patients with inflammatory arthritis.

Abstract
Background: Arthrosonography has proven to be more sensitive and reliable for the detection of synovitis than clinical examination, but a comprehensive examination of small joints is time-consuming. The automated breast volume scanner (ABVS) has been developed to allow automatic and reproducible series of consecutive B-mode pictures of the female breast. Objectives: To analyze the comparability of ABVS and conventional manual ultrasonography (mUS) for the detection of synovitis in hands and feet of patients with rheumatoid arthritis (RA). Methods: 45 patients with early and established active rheumatoid arthritis were recruited for this trial. All subjects were assessed clinically and by manual (Esaote MyLab70) and automated ultrasound (ACUSON S2000™ ABVS). The wrists, the metacarpophalangeal and proximal interphalangeal joints of the hands and the metatarsophalangeal joints of the feet were examined. Results: A total of 2 340 joint aspects were examined with both methods. ABVS detected 291 grade 1, 124 grade 2, 100 grade 3 cases of synovitis (515 in total) compared to 267, 180 and 145 cases of synovitis (592 in total) with mUS. 242 erosions and 52 cases of tenosynovitis were found by ABVS compared to 244 erosions and 99 cases of tenosynovitis found by mUS. Kappa coefficients for the agreement between both methods ranged from 0.51 in PIP joints to 0.71 in MCP joints. The correlations with clinical parameters as well as interrater agreements were comparable for both ultrasound methods. Conclusion: Based on the results, ABVS seems to be a promising technology for the comprehensive and time-saving assessment of synovitis in RA.

Maximum intensity projection with magnetic resonance imaging for evaluating synovitis of the hand in rheumatoid arthritis: comparison with clinical and ultrasound findings. Clin Rheumatol 2014; 33:911-7. [PMID: 24599675 DOI: 10.1007/s10067-014-2526-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2013] [Revised: 12/27/2013] [Accepted: 02/03/2014] [Indexed: 10/25/2022]
Abstract
Magnetic resonance imaging (MRI) with maximum intensity projection (MIP) is used to evaluate the hand in rheumatoid arthritis (RA). MIP yields clear visualization of synovitis over the entirety of the bilateral hands with a single image. In this study, we assessed synovitis with MIP images, clinical findings, and power Doppler (PD) findings to examine the clinical usefulness of MIP images for RA in the hand. Thirty RA patients were assessed for swelling and tenderness in the joints included in the DAS28, and both contrast-enhanced MRI for bilateral hands and ultrasonography for bilateral wrist and metacarpophalangeal (MCP) joints were performed. Articular synovitis was scored in MIP images, and the scores were compared with those for PD. The agreement on synovitis between MIP and conventional MR images was excellent. Palpation showed low sensitivity and high specificity compared with both MIP and PD images. There were joints that were positive in MIP images only, but there were no joints that were positive in PD images only. A statistically significant correlation between the scores of MIP and PD images was found. Furthermore, the agreement between grade 2 on MIP images and positive on PD images was 0.87 (κ = 0.73) for the wrist and 0.92 (κ = 0.57) for MCP joints. Using MIP images together with palpation makes detailed evaluation of synovitis of the hand in RA easy. MIP images may predict further joint damage, since they allow semiquantitative estimation of the degree of thickening of the synovial membrane.

Abstract
Psoriatic arthritis (PsA) is a chronic inflammatory joint disease which develops in patients with psoriasis. It is characteristic that the rheumatoid factor in serum is absent. Etiology of the disease is still unclear but a number of genetic associations have been identified. Inheritance of the disease is multilevel and the role of environmental factors is emphasized. Immunology of PsA is also complex. Inflammation is caused by immunological reactions leading to release of kinins. Destructive changes in bones usually appear after a few months from the onset of clinical symptoms. Typically PsA involves joints of the axial skeleton with an asymmetrical pattern. The spectrum of symptoms include inflammatory changes in attachments of articular capsules, tendons, and ligaments to bone surface. The disease can have divers clinical course but usually manifests as oligoarthritis. Imaging plays an important role in the diagnosis of PsA. Classical radiography has been used for this purpose for over a hundred years. It allows to identify late stages of the disease, when bone tissue is affected. In the last 20 years many new imaging modalities, such as ultrasonography (US), computed tomography (CT) and magnetic resonance (MR), have been developed and became important diagnostic tools for evaluation of rheumatoid diseases. They enable the assessment and monitoring of early inflammatory changes. As a result, patients have earlier access to modern treatment and thus formation of destructive changes in joints can be markedly delayed or even avoided.

Abstract
OBJECTIVE Tocilizumab (TCZ) is effective in patients with rheumatoid arthritis (RA) who are refractory to anti-tumor-necrosis-factor (anti-TNF) biologics. The Rheumatoid Arthritis Society Disease Activity Score in 28 Joints (DAS28) is used to evaluate the response to TCZ. However, DAS28 is inappropriate marker because TCZ normalizes C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) in the early stage of treatment. The aim of our study was to test the usefulness of magnetic resonance imaging (MRI)-based markers of response to TCZ treatment. METHODS Nine patients with RA who were refractory to anti-TNF inhibitors (six to infliximab, one to etanercept, one to adalimumab, and one to both) were assessed. MRI images of both hands were obtained by low-field extremity MRI at baseline, 20, and 44 weeks of treatment, in addition to assessment with DAS28-ESR. The effect of TCZ on RA was examined by compact MRI score (cMRIS). RESULTS All patients showed good or moderate response to TCZ treatment, as evaluated by significant reduction in DAS28-ESR at both 20 and 44 weeks (p < 0.001, each, relative to baseline). In contrast, MRI-based indexes (e.g., cMRIS, synovitis, edema, erosion scores) improved significantly at 44 weeks but not at 20 weeks. CONCLUSION Differences in response to TCZ therapy were determined based on the method of evaluation, suggesting that MRI-based markers are potentially useful for evaluating RA response to TCZ therapy.

Abstract
OBJECTIVE To evaluate the reliability and agreement of semi-quantitative scoring (SQS) and quantitative scoring (QS) systems. To compare the two types of scoring system and investigate the construct validity for both scoring systems. METHODS A total of 46 RA patients (median disease duration of 6.5 years) were enrolled in the study. They were investigated with colour Doppler ultrasound using the central position of the wrist. Disease activity score based on 28 joints (DAS-28) was determined for all patients using CRP. Two participants trained in the SQS system and two in the QS system evaluated the 46 anonymized images. All images were scored twice by each of the two assessors in order to assess both intra- and inter-reader reliability. RESULTS The reliability for the two systems were 0.964 for the QS, and 0.817 for the SQS, with a comparable inter-reader agreement for both scoring systems; 95% limits of agreement for the QS being between -7.7% and +6.7% on the colour fraction scale (0-100%), whereas SQS was between -0.8 and +0.8 on the ordinal scale from 0 to 3. There was a direct but non-linear relationship between the two modalities (Spearman's r = 0.73) and critical conceptual issues in the agreement between the scoring systems were revealed. The construct validity was poor for both systems with only a weak correlation to CRP. CONCLUSION High reliability and good agreement of both scoring systems were found when applied to the same patient cohort. Different scoring systems appear to be highly correlated.

Abstract
OBJECTIVES Although "clinical remission" has been a realistic goal of treatment in rheumatoid arthritis (RA), there is evidence that subclinical synovitis is associated with ongoing structural damage even after clinical remission is achieved. In the study reported here, we assessed whether ultrasonography (US) can predict progressive joint destruction during clinical remission of RA. METHODS Thirty-one patients with RA in clinical remission based on the disease activity score in 28 joints were recruited for this study. Bilateral wrists and all of the metacarpophalangeal and proximal interphalangeal (PIP) joints were examined by power Doppler (PD) ultrasonography (US), and the PD signals were scored semiquantitatively in each joint. The total PD score was calculated as the sum of individual scores for each joint. RESULTS Among 22 RA patients who maintained clinical remission during the 2-year follow-up period, seven showed radiographic progression. Radiographic progression was strongly associated with total PD score at entry, with all patients showing radiographic progression having a total PD score of ≥ 2 at entry and none of the patients with a total PD score of ≤ 1 showing any radiographic progression. There was no significant association of therapeutic agents with progressing or non-progressing cases. CONCLUSIONS PD-US detects synovitis causing joint destruction even when the patient is in clinical remission. Thus, remission visible on US is essential to reach "true remission" of RA.

Challenges to expanding the clinical application of musculoskeletal ultrasonography (MSUS) among rheumatologists: from a second survey in Japan. Mod Rheumatol 2011; 22:202-8.

Abstract
Our previous survey in 2008 revealed that only 22% of Japanese rheumatologists used musculoskeletal ultrasonography (MSUS) for patient management, because of insufficient educational opportunities. To clarify the current state of MSUS usage and to identify further challenges, we conducted a second survey between October 2010 through January 2011 by sending questionnaires to 200 randomly selected Japanese rheumatologists, consisting of 100 participants in a meeting in 2009 on imaging in rheumatic diseases and 100 board-certified rheumatologists. Among the respondents, a majority (85 and 67%, respectively) used magnetic resonance imaging (MRI). MSUS users had increased from 32 to 60% of meeting participants and from 11 to 27% of other rheumatologists. The majority of MSUS users had begun using MSUS within the previous 3 years. Whereas most respondents in the previous survey had been self-taught, in the current survey many had attended training courses or had received informal training from skilled users. Despite an increase in skills and equipment ownership, obstacles to implementing MSUS remained, most prominently a lack of time. In conclusion, training courses and informal training have contributed to the popularization of MSUS in Japan. To further increase MSUS usage, additional training opportunities and education about the advantages of MSUS will be needed.
