In the past reports, invariably irregularity and high-signal-intensity changes of the free edge of meniscus may lead to a false-positive MR imaging, in addition, MR imaging of the knee invariably missed small meniscal tears, tears and abnormalities of the meniscal free edge, and at times large, unstable tears, result in false-negative. In recent decades, new MR image of water-tissues and collagen-rich tissues, including cartilage, menisci and tendon, has undergone significant progress, which are biological MR image techniques for the characterization tissues .This study was to compare the diagnostic performance of SWI (Susceptibility Weighted Imaging) in the evaluation of meniscal tears at 3T MR with those of a T2 Mapping sequence, using phase value and T2 value as the quantitative parameters. The phase value was a good predictor to diagnose meniscal tears.
