The purpose of the present study is to optimize parameters of high-resolution 3D isotropic FSE fat-suppressed proton density-weighted images (FS PDWI) of the wrist in clinical settings within approximately 5 minute scan time. Optimal 3D isotropic FS PDWI of the wrist can be obtained with either 0.3 mm voxel size, 117 ETL, and 140-160 TI or 0.35 mm voxel size, 88 ETL, and 160-180 TI with less blurring, and acceptable S/N. Additional thin slice axial and sagittal images can be reformatted without extra scan time or degradation of image quality for a more complete assessment of the wrist structures.
