The Meckel's Diverticulum Nuclear Medicine Study depicts the uptake of pertechnetate within the abdomen. As a small molecule with a single negative charge, pertechnetate is secreted into the stomach as well as any ectopic gastric mucosa.


  • Detection and localization of a Meckel's diverticulum containing functioning gastric mucosa.
  • Detection and localization of other pathologic structures containing gastric mucosa.

Study Description

The patient is brought into the imaging area and the radiopharmaceutical is administered intravenously. A series of images of the abdomen will begin approximately five minutes later and will continue intermittently for 45 minutes post injection. On occasion, imaging may be extended to 60 minutes.
