Synopsis

Keywords: Pelvis, Tumor We have compare the performance of reduced field of view （rFOV）image reconstruction using image-space sampling function （IRIS）diffusion weighted imaging （DWI）sequence and full field of view (fFOV) single-shot echo-planar imaging （SSEPI）diffusion weighted imaging（DWI）sequence for rectal cancer patients. And found that compared to fFOV ssEPI-DWI sequence, rFOV IRIS-DWI sequence has a better resolution, reduced sensitivity artifacts, image distortion, and improved image quality in rectal cancer patients.
