Overview
On abdominal MRI, carcinoid tumor is characterized by nodular mass originating from the bowel wall or regional uniform bowel wall thickening with moderate intense enhancement on postgadolinium T1-weighted fat-suppressed images. Abdominal MRI scan may be performed to detect metastases of carcinoid syndrome to liver and mesentery.
