[Abstract] Objective We aimed to compare the image quality among conventional diffusion-weighted imaging (DWI), ZOOMit DWI, and RESOLVE DWI sequences for prostate imaging and to optimize the strategy to obtain high-quality diffusion MRI. Materials andMethods We retrospectively collected patients scanned with conventional DWI, ZOOMit DWI, and RESOLVE DWI imaging on the same scanner from April to october 2020, sixty patients were enrolled. The clarity, distortion, and artifacts of the images acquired in the three sequences were subjectively evaluated by two experience d radiologists. The outline of the prostate was manually delineated from the images by two experienced radiologists, and the SNR and CNR of the images were calculated. Differences in the subjective scores and objective parameters among the three sequences were compared.Results The subjective scores of clarity, distortion, and artifacts have significantly difference among the three sequences (P＜0.05). ZOOMit DWI had the highest clarity and the lowest distortion and artifacts. The the SNR (b=50) and SNR (b=1400) have significantly difference among the three DWI techniques (P＜0.05). The CNR (b=50) of the three DWI sequences have no difference (P＞0.05). The right-left diameter and the ratio of the anterior-posterior diameter/right-left diameter have significantly difference among the three DWI techniques (P＜0.05).Conclusions ZOOMit DWI sequence images were of higher quality. Therefore, ZOOMit DWI for prostate MRI is preferable for a better diagnosis.
