Figure 18a — T2 maps obtained in knee cartilage in a 51-year-old man after anterior cruciate ligament repair show higher T2 values (yellow) in the medial (a) and lateral (b) tibiofemoral compartments, findings indicative of deterioration of the integrity and orientation of the collagen network. Maps were obtained at 3.0 T with a sagittal 3D T2-weighted multiecho SE sequence (TR/TE = 9.3/3.1, 13.5, 23.9, 44.8; recovery time = 1500 msec; field of view = 14 cm; matrix = 256 × 192; section thickness = 3 mm; bandwidth = 31.25-kHz). Scale is in milliseconds.
