The blood supply of meniscus is an essential indicator for the prognosis of meniscal problems. With a favorable blood supply of the teared meniscus, it’s tend to preserve the meniscus as much as possible at partial meniscetomy and meniscal repair. Intravoxel incoherent motion (IVIM) theory provide information about microcirculation of blood in addition to the pure molecular diffusion. The perfusion information detected with IVIM is emphasized on microvascular bed, which is the typical blood supply pattern of meniscus. In this study, IVIM model were used to estimate the change of vasculature in normal, degenerated and teared meniscus.
