Complementary Assessment of Abdominopelvic Disorders with PET/CT and MRI

This article reviews the current performance and status of PET/CT and MR imaging in four different abdominopelvic malignancies: cervical, pancreatic, and rectal cancers and liver metastases, as well as in Crohn's disease. The authors discuss the complementary aspects of these imaging techniques to evaluate the nature of the lesion, its local extent, and distant spread. These disease conditions represent pertinent clinical models in which PET/MRI may, if and when available, constitute a powerful tool in the management of patients.
