7 T MRI knee protocol with turbo spin echo (TSE) sequences at the authors' institution. Although at lower field strength, TSE sequences are the mainstay of musculoskeletal MRI; at 7 T MRI, severe chemical shift artifacts and signal intensity inhomogeneities needed to be overcome for implementing TSE sequences. A, Coronal T1 sequence, (B) coronal proton density (PD) fat-saturated (fs) sequence, (C) sagittal PD fs sequence, and (D) axial PD fs sequence. Note that the small cartilage delamination (B) and superficial defects (C) of the femoral cartilage (arrowheads in inserts) are well depicted on high-resolution 7 T MRIs.
