PET/MR Detects Prostate Cancer Recurrence

An 11C-choline PET/MR protocol for the restaging of prostate cancer was well tolerated by patients and detected significantly more recurrences than PET/CT, according to new research. PET/MR was particularly good at detecting small local recurrences.

In theory, magnetic resonance imaging is more beneficial than computed tomography for prostate cancer restaging because it provides higher soft-tissue contrast. "In the analysis of recurrent disease, it would potentially have a higher detection rate," said lead investigator Matthias Eiber, MD, a radiologist from the Technical University Munich in Germany.
