Tumour scintigraphy – ¹²³I-mIBG
A safe examination that helps detect rare tumours
What is mIBG scintigraphy?
This special examination is used to visualise certain rare tumours of the nervous and glandular tissue, such as adrenal tumours (phaeochromocytoma), paragangliomas or tumours in children (neuroblastoma).
It uses a substance called ¹²³I-mIBG, which is similar to noradrenaline (a substance normally used by the body in the nervous system). If tumour cells absorb this substance, they can be visualised using a special camera.
When is the examination performed?
- When a tumour of the adrenal glands or other parts of the nervous tissue is suspected.
- When monitoring the effectiveness of treatment.
- When deciding whether radioactive iodine (¹³¹I-mIBG) treatment is appropriate.
How is the examination performed?
- A small amount of the radioactive substance ¹²³I-mIBG is injected into a vein.
- Imaging usually takes place after 4 and 24 hours (sometimes after 48 hours). Each scan takes about an hour and is painless.
- Doctors will assess whether the tumour cells are absorbing the substance and where exactly they are located.
How to prepare
- It is necessary to stop taking certain medications (e.g. some high blood pressure medications or antidepressants). Your doctor will inform you of everything in good time.
- No special diet or other preparations are necessary.
Is the examination safe?
Yes. The radiation exposure is low and the method has been used for many years in specialised centres around the world. Pregnant and breastfeeding women should consult their doctor about the suitability of the examination.
