Magnetic resonance imaging of bilateral hands is more optimal than MRI of unilateral hands for rheumatoid arthritis.

Mo YQ, et al.

J Rheumatol. (2018); 45(7):895–904

Unilateral MR imaging of either the dominant or more actively involved hand has been suggested as a time/cost savings method to determine disease activity of patients with rheumatoid arthritis (RA). In this study, the frequency of MR detectable hand/wrist rheumatoid arthritis (RA) synovitis, osteitis and erosion, as judged by the RAMRIS (rheumatoid arthritis MRI scoring) system, was compared for unilateral and bilateral MR imaging. Pre- and post-contrast MR imaging of both hands of 138 consecutive patients with active RA of was performed simultaneously at 3 T with the hands prone, side by side, within an 8 channel head coil (total imaging time 23 ± 5 min). Using a 128 mm FOV and 0.4 mm in-plane resolution, the wrists to MCP joints could be included in 120 (87%) patients (mean age 52 years, range 44–61 years; 79% female);...
