The study was performed to compare various two-dimensional and three dimensional MR sequences at 1.5T and 3T for evaluating the articular cartilage in human cadaveric wrist joints. Image quality and diagnostic performance was higher at 3T than at 1.5T. FGRE at 3T was the best sequence for evaluating articular cartilage and had the highest cartilage SNR, highest CNR between cartilage and bone, highest subjective rank for image quality, and highest diagnostic performance for detecting cartilage lesions.
