Multiparametric MRI in Evaluating Cancer Stage and Helping Treatment Planning in Patients With Prostate Cancer

PRIMARY OBJECTIVES: I. To estimate the diagnostic performance as quantified by the area under the ROC curve to detect aggressive prostate cancer. II. To develop a risk prediction model by incorporating overall PI-RADS, PSA, Gleason score and clinical stage to predict the presence of aggressive prostate cancer. SECONDARY OBJECTIVES: I. To evaluate the diagnostic performance of the individual PI-RADS score of each MRI parameter (T2W, DWI and DCE), as determined by local imaging review. TERTIARY OBJECTIVES: I. All clinical data including magnetic resonance (MR) images will be banked for future exploratory research aims. OUTLINE: Patients undergo mpMRI within 3 months prior to schedule surgery. After completion of study, patients are followed up until radical prostatectomy pathology is reported and finalized.
