Overview
Abdominal CT scan may be helpful in the diagnosing pancreatic involvement of multiple endocrine neoplasia type 1. Findings on CT scan suggestive of pancreatic involvement of multiple endocrine neoplasia type 1 include thickened stomach rugal folds, multiple gastric nodules and calcified or cystic pancreatic tumors.
CT
- CT is used for suspected gastric, enteric and pancreatic neuroendocrine tumors with pre and post IV iodinated contrast.[1]
- Bowel distension with fluid, either by oral intake (CT enterography) or via an nasojejunal tube (CT enteroclysis), improves detection of primary gastrointestinal neuroendocrine tumors.
