I-123/I-131 MIBG examination

 

The aim of the examination is to determine the location and extent of the so-called neuroendocrine tumor which is presumably present in the patient’s body. In an intravenous injection we administer a radioiodine (I-123)-containing substance called MIBG into the blood, which reaches and bounds to the cells of the neuroendocrine tumor. 24 hours later we take images of the whole body with the help of a special camera. This camera detects the radioactivity bound in the body and through this the location and extent of the tumor.

Preparations

Keeping a special diet is not necessary.
Certain medications may interfere with the therapy. If the patient takes any kind of drugs, the therapist has to inform them 4-6 weeks (!) before the therapy about taking which medications has to be suspended temporarily.
If the patient knows that any of his/her family members (siblings, parents, grandparents) has or had neuroendocrine tumor (thyroid, adrenal or carcinoid tumor, etc.), they have to inform the therapist and our colleague in the isotope laboratory.
