 The patients follow standard treatment and follow-up after the PETMRI exam, which will be determined by the patients treating urologist andor oncologist. Data from histopathology, clinical follow-up and follow-up imaging will be collected to establish a reference standard that defines the presence or absence of disease for each patient. The imaging findings will be compared with the reference standard to assess the sensitivity and specificity. The diagnostic accuracy of combined PETMRI and MRI-only the current clinical standard will be compared.
