Popis: To quantify Tofts model (TM) and shutter-speed model (SSM) perfusion parameters in prostate cancer (PCa) and noncancerous peripheral zone (PZ) and to compare the diagnostic performance of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) to Prostate Imaging and Reporting and Data System (PI-RADS) classification for the assessment of PCa aggressiveness.Fifty PCa patients (mean age 60 years old) who underwent MRI at 3.0T followed by prostatectomy were included in this Institutional Review Board-approved retrospective study. DCE-MRI parameters (KDCE-MRI parameters were significantly different between TM and SSM and between PZ and PCa (P0.037). Diagnostic performances of TM and SSM for differentiation of PCa from PZ were similar (highest AUC TM: KSSM DCE-MRI did not increase the diagnostic performance of DCE-MRI for PCa characterization. PI-RADS outperformed both TM and SSM DCE-MRI for identification of aggressive cancer.3 Technical Efficacy: Stage 2 J. MAGN. RESON. IMAGING 2017;46:837-849.
