MIBG Scan is a nuclear medicine imaging test that utilizes a radioactive tracer known as iodine-123-metaiodobenzylguanidine (MIBG) to assess the function and detect abnormalities in the adrenal glands and certain types of nerve cells. It is commonly used to identify tumors such as pheochromocytomas and neuroblastomas.The adrenal glands are small, triangular-shaped glands located on top of each kidney. They produce hormones that regulate several functions of the body, including blood pressure, metabolism, and stress response. On the other hand, nerve cells are essential components of the nervous system, which controls and coordinates body activities. MIBG is a compound that resembles a hormone called norepinephrine, and it is taken up by adrenal cells and certain nerve cells. When labeled with a radioactive isotope, it can be detected by special cameras to provide images of the structures it is absorbed by.

An MIBG scan is particularly useful in cases where a tumor originating from the adrenal glands or nerve cells is suspected. It helps in not only detecting the presence of a tumor but also in determining its location and size.
Medications: Inform your doctor about any medications you are taking. Certain medications might interfere with the tracer and affect the results. Your doctor might ask you to stop taking some medications a few days before the test.
Allergies: Inform the medical staff if you are allergic to iodine, as MIBG contains iodine.
Dietary restrictions: You may be asked to follow a low-iodine diet for a few days before the scan.
Clothing: Wear comfortable and loose-fitting clothes. You might be required to change into a hospital gown for the procedure.
Pregnancy and Breastfeeding: If you are pregnant or breastfeeding, inform the healthcare staff as the test uses radioactive materials.
The scan is considered safe as it uses a small amount of radiation. However, it’s important to discuss any concerns with your doctor, especially if you are pregnant or breastfeeding.
There might be a slight pinch during the injection, but the procedure itself is painless.
The imaging procedure can take several hours, and you might need to return for additional images up to 48 hours after the injection.
This is to ensure that the thyroid gland doesn’t take up the MIBG, which can interfere with the test results.
You can usually resume your normal activities. It’s a good idea to drink plenty of water to help flush the radioactive tracer out of your system.
This could indicate the presence of a tumor or an area of increased activity in the adrenal glands or nerve cells.
Yes, the information from the scan can help your doctor to develop a treatment plan.
This depends on your condition. Your doctor will advise you based on your specific situation.
You should see an endocrinologist or oncologist, depending on the findings.
Inform the medical staff if you are claustrophobic or anxious about the procedure. They can provide you with advice or medication to help you relax.
The MIBG Scan is an invaluable tool in the diagnosis and management of tumors arising from adrenal glands and nerve cells. If your doctor recommends this test, it is important to follow all the instructions and to communicate any concerns or questions you may have regarding the procedure. The insights gained from the MIBG Scan can be vital in ensuring the most effective treatment plan is chosen for your condition.
