11C-Choline Positron Emission Tomography/Computerized Tomography for Preoperative Lymph-Node Staging in Intermediate-Risk and High-Risk Prostate Cancer: Comparison with Clinical Staging Nomograms

Conventional imaging (CI) techniques are inadequate for lymph node (LN) staging in prostate cancer (PCa). To assess the accuracy of 11C-Choline positron emission tomography/computerized tomography (PET/CT) for LN staging in intermediate-risk and high-risk PCa and to compare it with two currently used nomograms. From January 2007 to September 2007, 57 PCa patients at intermediate risk (n = 27) or high risk (n = 30) were enrolled at two academic...
