This study explored and compared the performance of reduced-FOV diffusion-weighted imaging (rFOV DWI), readout-segmented echo-planar-imaging (rs-EPI) DWI, and conventional single-shot (ss)-EPI DWI techniques for diagnosis of cervical cancer. Image quality was assessed by two radiologists; rFOV DWI and rs-EPI DWI achieved significantly better image quality and clinical utility at both b=50 s/mm2 and b=1000 s/mm2 compared with ss-EPI DWI, and rFOV DWI outperformed rs-EPI DWI in terms of artifacts, overall image quality, and clinical utility.
