An MIBG scan is a nuclear medicine scan that involves an injection of a radioactive medication (radiopharmaceutical) called iodine-123 meta-iodobenzylguanidine – MIBG for short. The radiopharmaceutical is injected into a vein usually on the inside of the elbow.
A special gamma camera (a type of scanner) takes images or pictures to confirm if there are tumours (a lump or growth) called neuroendocrine tumours. These tumours involve specific types of nerve tissues and most commonly include pheochromocytomas (a rare tumour of the adrenal gland – which is located above and on the surface of the kidneys) and neuroblastomas (cancers that affect nerve tissue). Neuroblastomas usually begin in the adrenal gland, but might also be found elsewhere in the body.
