Diffusion imaging is part of the standard MR imaging protocol for prostate cancer diagnosis. Conventional echo planar imaging (EPI) diffusion sequence has limitation on image resolution and additionally suffers from image distortion. The present study introduces a new stimulated echo based 3D diffusion preparation turbo spin echo sequence (DPsti-TSE) to achieve high-resolution and distortion free image. The sequence is also proved to be immune to eddy currents.
