Diagnostic Accuracy of Diffusion-weighted MRI in comparison to Histopathology for Detection of Lymph Node Metastases in Normal Sized Pelvic Lymph-nodes in Patients with Bladder or Prostate Cancer

arrow). B (middle): Identical axial plane representing the ADC map. The mean ADC of the lymph node (black arrow) was measured with 78 x 10-5 mm/sec. C (right): Axial 3D T1-w SPACE reconstruction allowing to match the hyperintensive structure with a suspicious lymph node, which was correctly classified as positive from all readers. Size of the metastasis: 2mm x 2mm.
