The area under the ROC curve (AUC) of different b values distinguishing high-risk group from low-risk group of Gleason of prostate cancer were 0.651, 0.656, 0.692 (reader1) and 0.658, 0.653, 0.695 (reader2), respectively. The diagnostic efficacy of b value (3000 s/mm2) is the highest....
eADC values, BpMRI score and mpMRI score were effective indicators in diagnosis of clinical significant prostate cancer (P<0.001). The AUC values of ADC value and eADC value were 0.888 and 0.931 respectively, but...
(r一 一 0.439,P < O.01).The difference in ADC value between Gleason score of 6-mark group and≥ 7一mark group was statistically significant(F一 382.359,P< O.O1). Conclusion MRI ADC has a high value in the diagnosis of prostate cancer,it has a certain predictive effect on the degree...
