title: [Contrast medium sonography of neuroendocrine tumors of the gastroenteropancreatic system].
abstract: Ultrasonography is at present the primary diagnostic imaging method in patients with abdominal complaints. The innovations in echo enhancers in the last decade in connection with improved software and hardware have substantially extended the diagnostic spectrum of ultrasonography. Thus contrast-enhanced sonography with pulse inversion technology at low mechanical index allows a continuous evaluation of the perfusion of organs and tumors. Neuroendocrine tumors represent a heterogeneous group of endodermal/epithelial tumors, which are often hypervascularized. The morphology and the perfusion behavior of neuroendocrine tumors should be known because the therapeutic options differ substantially from those of other tumors. Contrast-enhanced sonography has already proven to be a valuable alternative in the diagnosis of neuroendocrine neoplasms and their metastases in relation to the established radiological procedures.
