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 kappa 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 kappa 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: 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.
