    Abstract
  • ObjectiveTo investigate the application value of 1.5 T magnetic resonance diffusion weighted imaging (MR DWI) in evaluating benign and malignant prostate lesions.MethodsThe relevant data of 136 patients with prostate lesions admitted to the hospital from October 2017 to August 2020 were retrospectively analyzed. All patients were subjected to MR DWI examination, and the diagnostic value of DWI in benign and malignant prostate lesions was analyzed. The ADC value, eADC value, and DWI semi-quantitative classification of patients with benign and malignant prostate lesions were compared.ResultsTaking pathological examination as the golden standard, the sensitivity, specificity and accuracy of DWI for diagnosing malignant prostate lesions were 95.16%, 98.65%, and 97.06%, and the Kappa value was 0.941. The ADC value of malignant lesions was significantly lower than that of benign lesions, and the eADC value was significantly higher than that of benign lesions (P < 0.05). ROC curve showed that the AUC values of ADC value, eADC value and combination of the two for diagnosing benign and malignant prostate lesions were 0.902, 0.967, and 0.990, respectively. DWI semi-quantitative classification of patients with malignant lesions was dominated by grade 4-5, which of patients with benign lesions was dominated by grade 1-3 (P < 0.05).Conclusion1.5 T MR DWI is of great value in evaluating benign and malignant prostate lesions.
