Synonym/Acronym:
Adrenal scintiscan, adrenal scintigraphy, metaiodobenzylguanidine or MIBG scan.
Rationale
To assist in the diagnosis of adrenal gland tumors (adrenocortical cancer, adenomas, neuroblastomas, and pheochromocytomas).
Patient Preparation
There are no food, fluid, or activity restrictions unless by medical direction. A number of medications may interfere with MIBG radionuclide uptake, most commonly ACE inhibitors, amiodarone, antihypertensives (reserpine, guanethidine, labetalol), calcium channel blockers, decongestants (ephedrine, phenylephrine, phenylproanolamine, pseudoephedrine), opioids, sympathomimetics (amphetamines, cocaine, epinephrine, methamphetamine, norepinephrine), and tricyclic antidepressants. These medications may be ordered to be withheld by medical direction prior to the scan. No procedures using barium contrast medium should be scheduled before this procedure. Protocols may vary among facilities.
Normal Findings
- No evidence of tumors
- Normal bilateral uptake of radionuclide and secretory function of adrenal cortex.
