Validation of 3 T MRI including diffusion-weighted imaging for nodal staging of newly diagnosed intermediate- and high-risk prostate cancer

•Validation of 3 T MRI DWI for lymph node staging of mainly high risk prostate cancer. •Patients correctly diagnosed with metastasis had many and large involved nodes. •Imaging detected 55% of patients with lymph node metastases. •Among patients without lymph node metastases, 10% were misinterpreted as positive. Aim To prospectively validate 3 T magnetic resonance imaging (MRI) including diffusion-weighted imaging (DWI) for preoperative lymph...
