Meckels Scan

About the Meckels Scan..

Meckel's diverticulum is the most common congenital abnormality of the gastro intestinal tract, present in 2% of the population. It consists of a small pouch in the wall of the intestine, near the junction of the small and large intestine, made of the type of tissue found in the stomach (gastric mucosa). Gastro intestinal bleeding is the most common complication in the paediatric age group.    

99mTc-Pertechnetate is concentrated by the gastric mucosa, therefore imaging of the abdomen following IV injection of pertechnetate should demonstrate any areas where there is increased tracer uptake. The Meckels scan is a simple, safe and noninvasive diagnostic procedure to show ectopic gastric mucosa, which is present in most cases of symptomatic Meckel's diverticulum. The technique will only detect diverticulae with significant ectopic gastric mucosa.
