Figure 6


Fig. 5B —48-year-old man with arthroscopic finding of medial meniscal tear. Coronal T2-weighted fat-suppressed fast spin-echo MR image (TR/TE, 4,000/60) shows nonlinear marrow edema in medial femoral condyle and medial tibial plateau. Subchondral marrow edema is present in medial femoral condyle (arrow). Ill-defined marrow edema around vascular channels of medial femoral condyle and medial tibial plateau is consistent with perivascular edema (arrowheads).
