Nuclear Gastrointestinal Scans
Meckel Scans
A Meckel scan is used to identify ectopic gastric mucosa (as in a Meckel Diverticulum ) by using an injection of 99mTc pertechnetate, which is taken up by mucus-secreting cells of the gastric mucosa. Focal uptake outside of the stomach and in the small bowel indicates a Meckel diverticulum.
