Adrenal Gland Scan

Adrenal gland scan is also known as adrenal scintiscan, adrenal scintigraphy, or metaiodobenzylguanidine (MIBG) scan.

Adrenal gland scan assists adrenal gland tumors including adrenocortical cancer, adenomas, neuroblastomas, and pheochromocytomas.

The normal findings related to adrenal gland scan include lack of evidence for tumor, normal bilateral uptake of radionuclide, and normal secretory function of adrenal cortex.

Glossary:

Adenomas: A non-cancerous epithelial tumor with glandular origin.

Metaiodobenzylguanidine (MIBG): MIBG is a radioisotope and a guanithidine analog that is similar to nor-epinephrine. It attaches to specific tumor cells.

Neuroblastomas: Rare types of cancerous tumors developing from immature nerve cells, usually starting in adrenal glands.

Pheochromocytomas: Rare types of adrenal gland tumor resulting in the release of large amount of epinephrine and nor-epinephrine.
