↵2-150 Second study between 11 and 16 weeks (mean (SD) 14 (1.4)) after baseline study. ^†Patients did not receive intra-articular therapy after the first study. ^‡Patient declined follow up. NS=not studied; NC=not completed because of patient claustrophobia; CNA=completed study though not analysed because of either: (1) inadequate synovial ROI enhancement resulting from a tissued iv injection, (2) inadequate synovial ROI image enhancement because of poor localisation of contrast within the synovial ROI throughout the dynamic image series, (3) excessive patient movement.
