The main purpose of this work was to demonstrate the feasibility of acquiring high resolution, isotropic 3D-sodium knee images of healthy and OA patients in vivo at 7T with clinically acceptable scan times via 3D-radial acquisition. The preliminary results suggest that the sodium imaging at 7T may be a viable potential alternative for OA imaging.
