T1 relaxation time was measured 90 minutes after intravenous and intra-articular Gd-DTPA administration to investigate the transport routes of gadolinium into articular cartilage. Significan differences were observed in superficial and full thickness cartilage, but not in deep cartilage. The present results suggest that most of the Gd-DTPA transports into articular cartilage from the synovial fluid regardless of the injection method.
