WHOLE-BODY DIFFUSION-WEIGHTED MAGNETIC RESONANCE IMAGING (WB-DW-MRI) VS CHOLINE-POSITRON EMISSION TOMOGRAPHY-COMPUTED TOMOGRAPHY (CHOLINE- PET/CT) for Selecting Treatments in Recurrent Prostate Cancer

This was a prospective, controlled, unicentric study, involving 46 consecutive patients from our centre who presented biochemical relapse after adjuvant, salvage or radical treatment with external beam radiotherapy, or brachytherapy. After initial tests ( bone scintigraphy, CT, pelvic MRI) 35 patients with oligometastases or without them were selected. 11 patients with multiple metastases were excluded from the study. WB-DW- MRI and choline-PET/CT was then performed on each patient within one week. The results were interpreted by specialists in nuclear medicine and MRI. If they were candidates for treatment with ablative SBRT (SABR) they were then evaluated every three months with both tests.
