[Abstract] Objective: By comparing the three sequences of T2WI and T2WI combined with DWI and DCE and their combined efficacy in the diagnosis of chronic prostatitis and prostate cancer, the optimal sequence of MRI in the diagnosis of prostate lesions was discussed.Materials and Methods: A total of 43 lesions were selected from 38 patients with low T2WI signal found in peripheral prostate gland by MRI examination from June 2014 to June 2020, and the clinical pathological and imaging data were retrospectively analyzed to summarize and analyze the diagnostic efficacy of each sequence and combined application.Results: There were 26 lesions in chronic prostatitis and 17 lesions in prostate cancer. The differences between the ADC values of inflammatory lesions, cancer foci and normal tissues were statistically significant by variance analysis (P<0.05). ADC value 0.92×10-3 mm2/s was used as the standard for detection of prostate cancer, with sensitivity of 96.2% and specificity of 88.2%. T2WI: The sensitivity and specificity of the diagnosis of prostate cancer were 52.94% and 69.23%, respectively, and the accuracy of the diagnosis of prostatitis and prostate cancer was 62.79%. The diagnostic efficacy of T2WI was compared with that of surgery and pathology, with poor consistency (Kappa=0.222). T2WI+DWI: The diagnostic sensitivity and specificity of T2WI+DWI for prostate cancer were 94.12% and 82.46% respectively, and the diagnostic accuracy for prostatitis and prostate cancer was 90.70%. The diagnostic efficacy of T2WI+DWI was compared with that of surgery and pathology, and the diagnostic efficacy was very satisfactory (Kappa=0.809), which was comparable to the combined application of T2WI+DWI+DCE.Conclusions: The diagnostic efficacy of T2WI+DWI is not significantly different from that of T2WI+DWI+DCE, so it is worth popularizing and applying.
