Can abdominal malignancies be evaluated with nuclear medicine studies ?
111 In pentetreotide is a somatostatin analog that targets a variety of neuroendocrine tumors including carcinoid tumors, pancreatic islet cell neoplasm, gastrinoma, pheochromocytoma, neuroblastoma, and paraganglioma. Whole-body planar and SPECT imaging are performed at 4 and 24 hours. The additional anatomic information provided by CT images, by fusion software, or with simultaneous acquisition with SPECT and CT provides localization of disease. In addition, if performed as SPECT/CT, the use of attenuation correction can improve detection of lesions deep within the body.
