[Abstract] Objective: To evaluate diffusion weighted imaging (DWI) in the differential diagnosis of prostate benign and malignant lesions.Materials and Methods: Of 47 cases, 29 patients with benign prostatic hyperplasia and 18 cases of prostate cancer patients underwent magnetic resonance imaging check, scanning sequences included conventional T1WI, T2WI, DWI and fat suppression imaging. All cases were confirmed by biopsy or surgery. Prostate size, lesion location, signal characteristics and tumor invasion situation were observed. The quantitative analysis of ADC and DWI was applied.Results: 13 of 18 cases with prostatic cancer located in the peripheral zone, the performance were peripheral zone nodules, flaky low signal area in T2WI; 8 cases were in the central zone or transition zone. The sensitivity, specificity, accuracy rate of DWI for the diagnosis of prostate cancer were 81.07%, 78.01%,80.11%, separately.Conclusion: DWI can improve the accuracy rate of diagnosis of prostate cancer.
