MIBG

MIBG scan is a scintigraphic study that uses metaiodobenzylguanidine, norepinephrine analog, labeled to iodine-123 or iodine-131. It is indicated in the investigation of pheochromocytoma.

MIBG is positive in:

• neuroblastoma
  • olfactory neuroblastoma
• carcinoid tumor
• paraganglioma
  • pheochromocytoma
• medullary thyroid carcinoma
• ganglioneuroma
• ganglioneuroblastoma

Some mild uptake can be physiologic in :

• liver

• urinary bladder 
• heart
• gastrointestinal tract
• adrenal glands
• brown fat 

Cardiac imaging studies with MIBG labeled to radio-iodine may be useful in the evaluation of cardiac toxicity from chemotherapy.
