Comparison between the application value of reduced FOV multi-shot echo-planar DWI and conventional single-shot echo-planar DWI

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.
