Scintigraphic studies in bleeding using 99mTc-labeled erythrocytes and occasionally 99mTc-labeled colloid for locating a source of bleeding in the lower GIT preoperatively or before angiography. Active bleeding can by focal accumulations of the tracer, which correspond to the intestinal anatomy and increase over time and move with peristalsis, are identified. These scintigraphic studies, for example in patients who who do not pre-cleaned intestine in significant bleeding, so the endoscopic view is highly restricted.

For the assessment of gastric emptying by giving the patient a radiolabeled (solid or liquid) test meal, and records the transport from the stomach with a gamma camera. Because this method can not differentiate between physical installation and gastroparesis, further diagnostic tests are usually connected if gastric emptying is delayed. The test is also useful for monitoring the effectiveness of promotorischen drugs (eg., Metoclopramide, erythromycin). Scintigraphic studies in bleeding using 99mTc-labeled erythrocytes and occasionally 99mTc-labeled colloid for locating a source of bleeding in the lower GIT preoperatively or before angiography.

These scintigraphic studies, for example in patients who who do not pre-cleaned intestine in significant bleeding, so the endoscopic view is highly restricted. A Meckel scintigraphy identified ectopic gastric mucosa (as in a Meckel’s diverticulum) using 99m Tc-pertechnetate, which is absorbed by the mucous cells of the stomach lining. A focal recording outside of the stomach and into the small intestine indicates a Meckel’s diverticulum.
