3T MRI can visualize synovium, cartilaginous, bone, and soft tissue more clearly than 1.5T MRI due to the enhanced SNR and the higher spatial resolution. The ability to delineate synovitis with high sensitivity can contribute to discriminating and managing early-stage RA patients. The constant coil development and technical solutions at 3T MRI would elucidate the mechanism of bone destruction in rheumatoid arthritis in more detail.
