MRI synovitis and bone lesions are common in acute gouty arthritis of the wrist even during the first attack

An additional score system, based on short tau inversion recovery (STIR) sequences (grade 0=thin hyperintense signal in the RAMRIS (rheumatoid arthritis MRI scoring system) areas, grades 1, 2 and 3=involvement 67%, respectively), was included as surrogate for synovitis evaluation.
