Three dimensional (3D), isotropic T2-weighted imaging of the prostate requires a long acquisition time. Here we propose a 3D T2-prepared multi-shot bSSFP acquisition with a variable density undersampled trajectory and TV-SENSE reconstruction. Results from a healthy volunteer study demonstrate that 3D 1 mm isotropic resolution T2-weighted images of the prostate can be acquired in 2 min 45 s, with image quality that is comparable to the clinical standard turbo spin echo sequences but only takes 1/3 of the acquisition time.
