Restricted Water Diffusibility as Measured by Diffusion-weighted MR Imaging and Choline Uptake in 11C-Choline PET/CT are Correlated in Pelvic Lymph Nodes in Patients with Prostate Cancer

摘要

11C-Choline-positron emission tomography (PET)/computed tomography (CT) is increasingly used in patients with prostate cancer. Another promising technique for assessment of tumor biology is diffusion-weighted MR imaging (DWI). The aim of the study was to compare the functional parameters standardized uptake value (SUV) in PET and apparent diffusion coefficient (ADC) value in DWI of lymph nodes in prostate cancer patients.
