[Multimodality MRI and PET for restaging prostate cancer after biochemical failure of the treatment]

Major improvements in the field of radiotherapy planning such as stereotactic radiation therapy, have recently been performed, aiming to the development of personalized therapeutic strategies in patients with biochemical failure of prostate cancer. However, this needs an early and accurate location of sites of recurrence. Development of multimodality magnetic resonance imaging (MRI) and positron emission tomography (PET) permits to consider this objective. Thus, it is worthwhile to apprehend the respective performance of these imaging techniques in order to rationalize their use. We propose a review of the recent literature organized by technique and by location, regarding the performance of multimodality MRI and PET for restaging of patients with biochemical failure of prostate cancer initially treated with curative intent.
