An Investigational Scan (Dual Energy CT) in Detecting Gastrointestinal Carcinoid Tumors

Study Purpose

This trial studies the use of a special type of computed (CT) scan called dual energy CT in detecting gastrointestinal carcinoid tumors. CT is an imaging technique that uses x-rays and a computer to create images of areas inside the body. Dual energy computed tomography is a technique used during routine CT scans to help obtain and process the image after the scan is complete. Doctors want to learn if dual energy computed tomography can help improve the detection of carcinoid tumors during routine CT scans.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years and Over
Gender All

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
