In the evaluation of uterine malignancy, conventional DWI based on single-shot echo-planar imaging (ss-EPI) is prone to imaging artifacts, including susceptibility artifacts from gas, imaging blurring, which limit its diagnostic value, especially in detecting and staging uterine malignancy. The purpose of this study is to compare the detection of uterine malignancy and image quality among DWI based on integrated slice-specific dynamic shimming (iShim), readout segmentation of long variable echo trains (RESOLVE) and ss-EPI sequence. Our results indicated that iShim DWI showed better image quality than ss-EPI and RESOLVE DWI in the terms of subjective image scores and objective quantitative metrics.
