This study evaluated a new diffusion weighted imaging (DWI) technique for assessing rectal cancer. Based on a population of 12 patients diagnosed with rectal carcinoma, images were acquired using both Read-out Segmented Echo-Planar Imaging (RESOLVE) and integrated slice-specific shimming (iShim)-DWI sequences using the same field of view (FOV) at 3T in assessment of rectal carcinoma. The quality of the images was compared based on independent review by radiologists plus parameter data analysis. The results showed that the image quality and lesion conspicuity of the iShim-DWI sequence were significantly better than RESOLVE DWI sequence in assessment of rectal carcinoma at 3T.
