Overview
Brief Summary
This research study will access the using of a radiotracer, 18F-choline PET/CT and MRI for prostate cancer in patients undergoing diagnostic prostate biopsy. Patients receive MRI guided prostate biopsies and metabolomic profiling of prostate biopsy tissues.
Detailed Description
This is an explorative diagnostic basic research study to assess the value of 18F-choline PET/CT and multi-sequence MRI for prostate cancer in patients undergoing diagnostic prostate biopsy. Patients will receive image-guided (targeted) prostate biopsies and metabolomic profiling of prostate biopsy tissues to evaluate underlying metabolic changes in comparison with pathological Gleason grading.
