A new isotropic 3D FSE sequence, 3D-FSE-Cube, is currently being developed for multiple structural imaging applications as an improvement to traditional 2D-FSE methods. This study aimed to optimize 3D-FSE-Cube for musculoskeletal evaluation of the knee at 3T. 146 scans from 7 healthy volunteers were acquired with systematically varied acquisition parameters and evaluated for SNR, CNR and image quality in comparison to a single reference standard. Regression analysis suggests that current clinical acquisition parameters produce close to optimal image quality.
