Fig. 4From: Morphological MR imaging of the articular cartilage of the knee at 3 T—comparison of standard and novel 3D sequencesA 59-year-old female with chronic knee pain. a Axial reformatted FLASH image shows extensive cartilage loss at the medial patella (arrow). Normal cartilage is seen on the lateral patellar facet (arrowhead). b Axial reformatted UTE subtraction image shows absence of high-intensity linear signal near the osteochondral junction at the medial patella (arrow). Normal UTE appearance of the osteochondral junction on the lateral patellar facet is demonstrated (arrowhead)Back to article page
