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.
MRI
On abdominal MRI, carcinoid syndrome is characterized by:[1]
- Nodular mass originating from the bowel wall or regional uniform bowel wall thickening with moderate intense enhancement on post-gadolinium T1-weighted fat-suppressed images.
- Mesenteric metastases presented as nodular masses with mesenteric stranding.
- Liver metastases may show hypointense precontrast T1- and hyperintense T2-weighted images.
- Liver metastases are commonly hypervascular.
