Radiologic Diagnosis of Neuroendocrine Tumors

Abstract

The radiologic work-up of a patient with a pancreatic endocrine tumor should follow a strict course. Ultrasonography as the first procedure should be followed by angiography, if possible. Negative ultrasonography should be followed by computed tomography (CT), which, whether positive or negative, is supplemented by angiography. Negative CT and angiography is followed by transhepatic venous sampling. In patients with suspected liver metastases from intestinal and pancreatic endocrine tumors, angiography may reveal more metastases than CT and ultrasonography.
