According to 2015 National Comprehensive Cancer Network (NCCN) guideline, medical imaging plays important roles for detection and staging for PCa, in addition to blood or urine biomarkers. Although there are a number of very different diagnostic imaging methods, e.g. transrectal ultrasound (TRUS), computed tomography (CT), magnetic resonance (MR) imaging and spectroscopy, or 18F-FDG positron emission tomography (PET), none of these have gained a dominant role as the optimum method for all clinical scenarios.The recently added armamentarium, PET/MR, might improve diagnosis in this regard.
Therefore, we conduct this trial to identify the ability of \[11C\]Choline PET/MR to evaluate the patients with prostate cancer, especially under the circumstance of elevated PSA level.
