Labelled Red Blood Cell (RBC) Scan for Hemangioma
- This test is highly specific for cavernous hemangiomas of the liver. The sensitivity for detecting large lesions of the liver (>2-3cm) is also high. Hemangiomas as small as 0.5 cm may be detected with SPECT.
Meckel's Diverticulum Scan
- To localize ectopic gastric mucosa in a Meckel's diverticulum as the source of unexplained gastrointestinal bleeding.
- the Meckel's scan should be used when the patient is not actively bleeding
Gastro-Intestinal Bleeding Scan
- To locate the bleeding site and to determine who requires aggresive treatment versus those who can be medically managed. ( it is usually in those patients that require urgent care that the bleeding site is identified)
- GI Bleeding scans should be done as soon as possible after the patient presents for medical care, since active bleeding is more likely at early times and is needed for correct localization.
Gastric Emptying Study
- nausea, vomiting
- upper abdominal discomfort, bloating
- chronic aspiration
- Suspected gastroparesis
- Poor diabetic control
- Gastroesophageal reflux
- Following response to therapy for previously documented motility disturbances
