Adrenal Medulla MIBG Scan

Your doctor has requested an MIBG scan. This booklet will answer some of the questions you may have. 

What is an MIBG scan? 

An MIBG scan is used for the localization of certain types of neuroendocrine tumors in the body. 

What is involved? 

You will be given three appointments for your test: 

On the first appointment (15 min), a technologist will explain the entire procedure to you and then give you the opportunity to ask any questions. You will then receive an injection of a radioactive tracer into a vein in your arm. There are no known side effects from this injection. You will have a waiting time of about 3 – 4 hours before your scan, during which you may leave the department. You can have your meals and you will be asked to drink more fluids. 

At your second appointment (2 hours) on the same day, we will scan your body. You will be asked to remove all external metal objects from your body and lie on our imaging table. The technologist will use a special detector called a gamma camera to scan your body from head to toe. We will also take some three-dimensional images of your body. This part of the test will take about 2 hours. 

You will return for your third appointment (2 hours) to have the same images repeated the next day. On occasion, you may be asked to come back 48 hours later for a fourth visit, if required by the Nuclear Medicine Physician, for the clarity of the scan. 

Do I need to prepare for the scan? 

  • Bring your Health card  
  • Certain drugs may interfere with this study and these should be discontinued prior to the administration of MIBG. The clerk who books your test will ask you for a complete list of the medications that you are taking. It is important that you also bring your list of medications to your first appointment. Please check with your physician before stopping any medication. 
  • You will be required to take potassium iodide capsules, beginning one day prior to the administration of the radiotracer. The Nuclear Medicine staff will provide a prescription for these capsules to your pharmacy. You can obtain the capsules from your pharmacy and start taking them on the start date indicated. Keep taking them until you have none left. 
  • For all your appointments, we would like you to dress in clothing that does not have any metal. Please refrain from wearing any jewelry. Please leave all valuables at home. 
  • Please notify our booking office at the time of scheduling your appointment if you have any concerns regarding claustrophobia, lying still, require a mechanical lift for transfer to the imaging bed, have a language barrier or any other special needs, so that appropriate arrangements can be made ahead to provide you with the best possible care. 

Will it hurt? 

Only the pinprick of the injection needle may hurt a bit. You may have had a blood test in the past. This is much the same. 

Is the radiation dangerous? 

The injection contains a small amount of radioactive tracer which emits gamma rays (these are similar to X-rays). The radiation dose is very low and will disappear by itself within approximately one week. The results of your scan will give your doctor useful information about your condition and will help them plan your treatment. The benefits of having the scan far outweigh any potential risk from the small radiation dose. 

Do I need to do anything after the scan? 

It is important that you continue taking the potassium iodide capsules even after the scan is done, until all the capsules are finished. 

If you are travelling across any borders in the two weeks after your scan, please ask us for further advice. Border crossings and airports have very sensitive radiation detectors which may pick up tiny amounts of radioactivity remaining after your scan. We will give you a letter that you can show to customs officials at border crossings or airports. 

Is there anything I should tell the staff before the injection? 

Certain drugs may interfere with this study, so it is very important for us to know about all of your medications. Please provide a current list of all your medications to the technologist before receiving the radiotracer. 

Please tell us if you are pregnant or breastfeeding. 

What about breastfeeding? 

Breastfeeding will need to be interrupted for at least 48 hours and may need to be discontinued entirely. It is vital that you ensure that we are aware if you are pregnant and/or breastfeeding. 

How will I get the results of my scan? 

A specially trained doctor will examine the pictures. This is normally done soon after the end of the scan. A report is then sent to the doctor who asked us to do the scan. Your doctor will normally receive the report within one week. You will also have access to the report on MyChart as soon as it is released. 

If you have questions about the scan results or report, please contact your doctor directly. They are best able to interpret the report for you. 

Will this test cost me money? 

No. This test is paid for by the healthcare system. The test costs over one thousand dollars, so please notify the department at 613-761-4831 if you cannot make your appointment. 

What should I do if I cannot make my appointment? 

If you cannot make you appointment, it is important that you notify the department at 613-761-4831 as soon as possible. Failure to make your appointment results in wasting of expensive materials that are ordered especially for your appointment and also reduces availability to other patients. Missed appointments may also result in delays of your treatments.
