Abstract
Materials and methods A total of 322 patients with BRPC underwent either a PET-CT or a MR-PET examination (Siemens Biograph mMR) after injection of about 150 mBqGa-PSMA. Images were evaluated in cosensus by one experienced nuclear medicine physician and one radiologist. Pelvine lymphnode dissection was performed in most of the patients according to a predefined template with 8 fields. Lymphnode involvement was evaluated according to a 5 point scale with a patientand a field-based analysis. These findings were stratified according to PSA-values.
Highlights
In this study we evaluated the accuracy of 68Ga-PSMA in patients with rising PSA after radical prosatectomy, so called “biochemical recurrent prostate cancer” (BRPC)
Images were evaluated in cosensus by one experienced nuclear medicine physician and one radiologist
In comparison to the MR-images alone MR-PET was of superior diagnostic value

From International Cancer Imaging Society Meeting and 15th Annual Teaching Course (ICIS 2015) London, UK. Aim of study In patients with prostate cancer increased levels of PSMA can be measured. In this study we evaluated the accuracy of 68Ga-PSMA in patients with rising PSA after radical prosatectomy, so called “biochemical recurrent prostate cancer” (BRPC)
