Review the current status and clinical utility of PET/MRI in gynecological tumors. Compare the diagnostic accuracy of fused PET/MRI regarding PET/CT and MRI

FDG/PET is now accepted as a powerful imaging modality for evaluating various kinds of malignancies. However, the contrast resolution of CT for different tissues is limited,especially in pelvis,even when full-dose exposure and contrast medium are employed. In contrast,MRI has several advantages over CT,such as excellent tissue contrast and involves no radiation exposure.Most papers try to compare these techniques, but in our experience they both are complementary in the management of these patients.Meanwhile PET/CT is superior in the diagnosis of ganglionar disease; MRI with DWI presents higher accuracy in local preoperative staging and distinguishing early postradiation changes from recurrent tumor.Both techniques can be used as biomarkers of tumor response and present high accuracy in the diagnosis of local recurrence and peritoneal dissemination, with complementary roles depending on histological type, anatomic location, and tumoral volume.Fused PET/MRI, which complements the individual advantages of MRI and PET, is a valuable technique for assessment of the primary tumor and nodal staging in patients with gynecological cancer.
