This study aims to assess the clinical feasibility of high b value iZOOM on prostate and to validate whether it is superior to regular DWI at 3.0 T with 58 patients recruited in the study. The scan protocol included iZOOM and DWI with b value of 2000s/mm2. Subjective and objective evaluation was carried out from three aspects: the basic image quality, the display of lesions, and the overall image quality. Our study found that with the same high b value, iZOOM had better comprehensive image quality, less artifact and distortion yet similar contrast compared with regular DWI.
