This study aims to demonstrate the feasibility of iZOOM using a 2D RF pulse EPI sequence in the application of prostate DWI and the optimization of iZOOM at 3.0 T MRI. 58 patients took prostate MRI examination with 3 iZOOM sequences (1. b=1000, resolution: 1.4×1.4mm; 2. b=1000, resolution: 1.0×1.0mm; 3. b=2000, resolution: 1.4×1.4mm). Images were evaluated with the basic image quality, the display of lesions and overall image quality. The result shows iZOOM is feasible on prostate DWI. High b value and high resolution iZOOM are both favored by radiologists.
