Renal Scan

A Renal scan is a simple and painless way of taking pictures of the blood flow and function of your kidneys using a radioactive tracer. 

When you arrive in the department, a technologist will explain the entire procedure to you and then give you the opportunity to ask any questions. You will be asked to lie on our imaging table. The technologist will give you an injection of a radioactive tracer into a vein in your arm. There are no known side effects from this injection. The technologist will then use a special detector, called a gamma camera, to take a series of images of your kidneys. The entire procedure will take about one hour. 

• Bring your Health card.
• You should arrive well hydrated by drinking at least 0.5 liters of water starting one hour before your appointment. You may empty your bladder as required.  
• 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.

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. 

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. 

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. 

Please tell us if you are pregnant or breastfeeding.

A specially trained doctor will examine the results of your test. This is normally done soon after the end of the test. A report is then sent to the doctor who asked us to do the test. 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. 

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. 

If you cannot make your 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.
