A 50-year-old female with surgically confirmed normal patellar cartilage, which was interpreted as grade 3 cartilage lesions by all readers using 3D SPACE and as normal patellar cartilage by all readers using the routine MR protocol. Axial 3D SPACE (a) shows an irregular patellar articular surface (arrow). Axial 2D TSE intermediate-weighted FS (b) image shows a smooth patellar articular surface. Poor image contrast on 3D SPACE images was considered the primary cause of the discrepancy
