Summary

The purpose of this study is to determine the effectiveness of whole-body diffusion-weighted magnetic resonance imaging (WB-DW- MRI) in detecting metastases by comparing the results with those from choline-positron emission tomography-computed tomography (choline-PET/CT) in patients with metastatic/oligometastatic prostate cancer. Patients with this disease profile who could benefit from treatment with stereotactic body radiation therapy (SBRT) were selected and their responses to these techniques were rated.

Detailed description

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.
