Your doctor has requested a Salivary Gland scan. This booklet will answer some of the questions you may have. 

What is a salivary gland scan? 

A Salivary Gland scan is a simple and painless way of taking pictures of your salivary gland using a radioactive tracer.  

What is involved? 

When you arrive in the Nuclear Medicine Department, a technologist will explain the entire procedure to you and then give you the opportunity to ask any questions. The technologist will also ask you to remove any jewelry around the area to be scanned. You will then be asked to lie on an imaging table and a special detector, called a gamma camera will be placed over your neck area. The technologist will then inject a small amount of radioactive tracer into a vein in your arm. There are no known side effects from this injection. This tracer will then be picked up by the gamma camera and a series of images will be taken for about 30 minutes. It is essential that you remain very still for the duration of the scan in order to avoid any blurring of the images. At one point during the images, the technologist will place a small amount of a harmless solution in your mouth that will stimulate your salivary glands.  

The entire test takes about an hour. 

Do I need to prepare for the scan? 

  • Bring your Health card. 
  • No special preparation is required. You will be able to eat, drink and take your medications as usual on the day of your scan.  
  • 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 after two days. 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? 

No special precautions are needed after the scan. If you are travelling across any borders in the seven days 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? 

Please tell us if you are pregnant 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 several hundred 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.
