This task force has produced a consensus-based comprehensive and practical framework on standardised procedures for MSUS imaging in rheumatology.

DECT and US have comparable sensitivity for the detection of gouty arthritis in a clinical setting. However, DECT results should be interpreted carefully, as there could be some false-negative findings.

Objective. Sonography, as compared with clinical assessment, is a sensitive tool for evaluating synovitis in rheumatoid arthritis (RA). However, differences between these assessment tools may depend on how joint activity (i.e., an active joint) is defined. The present study was undertaken to compare clinically active joints with sonographically active joints in patients with RA, applying different sonographic definitions of an active joint.Methods. Sonographic assessment of the finger and wrist joints (total of 11 joints) of each hand was performed in RA patients whose disease was in remission (Clinical Disease Activity Index <2.8; n ‫؍‬ 60). Gray-scale (GS) and power

Sonographic cartilage assessment in MCPs is closely related to anatomical cartilage thickness. Both JSW and JSN by radiography represent cartilage thickness in the MCP joints of patients with RA quite well. Thus, US is a valid tool for measuring MCT if radiographs are not available or in case of joint malalignment.
