Figure 7b. Subchondral osteophyte as a sign of cartilage damage. (a) Anterior radiograph shows a small osteophyte of the lateral femoral condyle (arrow). (b) Sagittal 3D spoiled GRE image shows the osteophyte in an area of cartilage damage (arrow). (c) Sagittal T2-weighted fast SE image shows the osteophyte (arrow). The full thickness of the remaining cartilage is difficult to see due to cartilage signal loss. (Reprinted, with permission, from reference 76.)
