What does MIBG stand for?
MIBG stands for meta-iodobenzylguanidine — a molecule that is actively absorbed by neuroblastoma cells. When radioactive iodine is attached to MIBG, the combination is referred to as I131-MIBG.
What does an MIBG scan show?
Definition: MIBG is a nuclear scan test that uses injected radioactive material (radioisotope) and a special scanner to locate or confirm the presence of pheochromocytoma and neuroblastoma, which are tumors of specific types of nervous tissue.
What is MIBG uptake?
Iodine 123 (123I) metaiodobenzylguanidine (MIBG) is the first-line functional imaging agent used in neuroblastoma imaging. MIBG uptake is seen in 90% of neuroblastomas, identifying both the primary tumor and sites of metastatic disease.
Is MIBG a radiation?
Although it looks like water, MIBG is actually a special medicine that contains radiation. Radiation used for therapy can be provided in two different ways. Typically, a machine delivers it from outside of the patient’s body. However, radiation also can be given inside the body through a central line or IV.
What should I avoid before MIBG scan?
The following list of drugs are some of the more commonly encountered medications in this group and should be withheld for 24 hours before the MIBG administration: opioids, tricyclic antidepressants, sympathicomimetics, amiodarone, reserpine, guanethidine, calcium channel blockers, and ACE inhibitors.
When should we do MIBG scan?
What are the generally accepted indications for an MIBG scan? Diagnosis of a suspected neuroendocrine tumour (phaeochromocytoma and neuroblastoma) when there is hormonal indication of one. Determine staging of a known neuroendocrine tumour. Determine suitability for MIBG therapy.
What is a Curie score?
A score of 3 was assigned for the soft-tissue region if disease occupied >50% of the chest or abdomen. A patient’s Curie score at each time point was calculated as the sum of scores over all individual sites, with a maximum score of 30.
What is Octreoscan used for?
An octreotide scan (also called a somatostatin receptor scintigraphy) is a test used to check the body for neuroendocrine tumor cells. This test is done in a Nuclear Medicine department, which is a type of radiology that uses radioactive materials to diagnose or treat diseases.
