Characterisation of hand small joints arthropathy using high-resolution MRI—Limited discrimination between osteoarthritis and psoriatic arthritis

Objective To test the hypothesis that microanatomical differences in joint disease localisation could be exploited using high-resolution MRI to better differentiate among rheumatoid arthritis (RA), spondyloarthritis/psoriatic arthritis (SpA/PsA) and osteoarthritis (OA) in clinical practice.
