Summary

This study looks at whether a special type of CT scan, called dual energy CT, can better detect carcinoid tumors in the digestive system. About 71 people with signs or confirmed carcinoid tumors will get this scan during a routine check-up. The goal is to see if this imaging method improves how well doctors can find these tumors.
