Brief Summary:

Primary objective:

To correlate the blood/urine metabolomic biomarkers with PET/MR imaging.

Secondary objectives:

  1. To evaluate the sensitivity and specificity of the PET/MR in diagnosis of prostate cancer.
  2. To examine the diagnostic performance among subgroups of defined high-risk and low-risk subjects.
  3. To interrogate the metabolomic alterations with the molecular PET/MR to develop workable panel biomarkers.

Condition or disease
Prostate Adenocarcinoma

Detailed Description:

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.

The newly diagnostic number for the high-risk PCa patients in our hospital annually is ~70, it is clinically feasible to recruit 40 patients a year since the study begins. The study could be completed in 3 years with 120 cases.

Primary Outcome Measures :
  1. Diagnostic Accuracy [ Time Frame: 1 year ]
    sensitivity, specificity, accuracy
