Plate 5-4 Left Midknee. Diagnostic MR. Plane cutting through a medial parasagittal plane of the knee that represents both cruciate ligaments. The MR pulse sequence make fat bright, muscle intermediate, and fibrous tendons or ligaments dark in signal. This view is very helpful in evaluating for cruciate ligament injury. Note the suprapatellar bursa is collapsed in its normal state. Radiographic Key: 1 Prepatellar bursa, 2 Patellar tendon, 3 Suprapatellar (quadriceps) bursa, 4 Articular cart...
