3T Perfluorocarbon-Filled Endorectal Magnetic Resonance Spectroscopic Imaging of Prostate

Objectives: The objectives of this study are to: 1) evaluate the feasibility of 3T MRSI of prostate in improving the spectral resolution, using a PFC-filled endorectal coil, 2) develop a systematic metabolic grading system for tumor detection by identifying the abnormal peak areas of Cho, Cr, Po, and Ci for the prostate carcinoma, specifically from PFC-filled endorectal 3T MRSI, and 3) evaluate the efficacy of the metabolic grading system in tumor detection. The long-term goal of the study is to provide an early prognostic indicator and means of monitoring the biologic status of the prostate cancer during the course of the disease.
