- W2382620121 abstract "Objective: To assess vascular kinetics using perfusion-weighted MRI(PWI) in the differentiation of prostate cancer in the peripheral zone. Materials and Methods: Fifty-one patients with low T2 signal nodules in the prostate peripheral zone underwent PWI-MRI at 3 T were included in these study. Ktrans, Kep and Ve were compared between prostate cancer and benign nodules. Receiver operating characteristic(ROC) curve analyses were performed to determine the diagnostic accuracy of Ktrans, Kep and Ve. Results: The average values of Ktrans, Kep and Ve for prostate cancer and begin lesions were(0.150±0.046) vs(0.086±0.037),(0.518±0.181) vs(0.325±0.142) and(0.288±0.147) vs(0.306±0.141), respectively. There was statistically significant difference in Ktrans, Kep between prostate cancer and begin noduless(P0.01). However, there was no statistically significant difference in Ve. The sensitivity, specificity for determining the prostate cancer of Ktrans, Kep were 86.11%、80.6% and 79.32%、75.9%, respectively. Conclusions: Quantitative assessment of vascular kinetics using PWI is useful in the differentiation of prostate cancer in the peripheral zone." @default.
