Eighteen patients with inflammatory lesions of the knee joints (ten with rheumatoid arthritis, eight with undiagnosed lesions) and two normal subjects were examined by MRI. In addition to spin-echo measurements, the signals from normal and pathological tissues were evaluated quantitatively by dynamic flash sequences following the injection of gadolinium DTPA. The latter method was able to distinguish active pannus from other proliferative synovial changes; the degree of activity could be related to synovial histology and relevant clinical features in eight patients. Areas of flat articular and subchondral pannus could be identified by the enhanced signal following the administration of gadolinium DTPA. Dynamic MRI is able to provide important information for the early diagnosis and follow-up of patients with rheumatoid arthritis.
