title: 11C-Choline-Avid but18F-FDG-Nonavid Prostate Cancer with Lymph Node Metastases on Positron Emission Tomography.
abstract: Choline is a new positron emission tomography (PET) tracer useful for detection of prostate cancer and metastatic lesions. We report a 70-year-old man with prostate cancer and multiple abdominal, pelvic, and inguinal node metastases. PET scans demonstrated accumulation of11C-choline in the primary tumor and lymph node metastases but no accumulation of18F-FDG. Choline PET/computed tomography may be useful for diagnosis of advanced prostate cancer with suspected metastatic lesions and treatment planning.
