Musculoskeletal MRI studies usually comprise of 2D-FSE sequences acquired in orthogonal planes. 3D-FSE enables isotropic voxel acquisition allowing reformations and decreased overall exam time. Thinner slice thickness in 3D-FSE also results in less partial volume artifact. We compare the clinical performance of 3D-FSE to 2D-FSE in evaluating the symptomatic upper extremity at 3.0T using arthroscopy as a reference standard. 3D-FSE showed similar performance to 2D-FSE in pathology identification in the upper extremity. The thinner slices of 3D-FSE, and the ability to reformat images in arbitrary planes, enabled optimal visualization of smaller and oblique pathology.
