Somatostatin Receptor Scintigraphy: Its Sensitivity Compared with That of Other Imaging Methods in Detecting Primary and Metastatic Gastrinomas: A Prospective Study

Somatostatin receptor scintigraphy is the single most sensitive method for imaging either primary or metastatic liver lesions in patients with the Zollinger-Ellison syndrome. Because of its sensitivity, simplicity, and cost-effectiveness, it should be the first imaging method used in these patients. For patients with negative results on somatostatin receptor scintigraphy, guidelines about the use of other imaging studies are proposed.
