The Value of Apparent Diffusion Coefficient Map based on PI-RADS v2 in Predicting Clinically Significant Prostate cancer

To determine the value of ADC map in identifying clinically significant prostate cancer, the ADC PI-RADS scores and mean ADC values of index lesion based on PI-RADS v2 were measured. ADC PI-RADS score may be good as overall PI-RADS v2 score in predicting clinically significant PCa. The clinically significant cancers had higher ADC scores and lower ADC values. An ADC value of 619-889×10-6 mm2/s may be useful in the identification of clinically significant cancers.
