Nuclear Medicine
Nuclear medicine is a diagnostic imaging tool that uses small amounts of radioactive material to capture images of different organs within the body.
What is nuclear medicine?
During a nuclear medicine scan, radioactive material is administered, usually by injection, and will accumulate in a specific organ. The radioactive material gives off a signal that is detected by a gamma camera. This creates images which are used to diagnose disease.
While other diagnostic imaging procedures such as Computed Tomography (CT), Magnetic Resonance Imaging (MRI) and X-rays allow images of physical structures, nuclear medicine scans can help determine how a particular organ functions. For more information on Nuclear Medicine scans visit RadiologyInfo.org.
What are the benefits and risks of a nuclear medicine scan?
For more than 50 years, Nuclear Medicine scans have been performed and provide physicians with detailed images of what is happening in the body at the molecular and cellular level. These images assist with diagnosis and treatment of a disease.
Nuclear medicine procedures use small amounts of radioactive material to create these images. The radiation risk involved in these procedures is minimal when compared to the potential benefits of the diagnosis from the scan.
Please speak with your referring physician if you have concerns about the risks versus the benefits of the scan he/she has ordered for you.
Can I have an allergic reaction to radioactive material?
Allergic reactions to radioactive material are extremely rare. Nuclear medicine scans may require the use of additional medications which carry small risks of allergic reaction. Please inform your technologist of your allergy history prior to your scan.
Nuclear medicine radioactive materials are not the same as the contrast material used for Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) scans. It is safe for patients who have had previous allergic reactions to CT and MRI contrast material to have nuclear medicine scans.
Is it safe for me to have a nuclear medicine scan while pregnant or breastfeeding?
Let your physician know if you are pregnant or breastfeeding.
Nuclear medicine scans are not routinely performed while pregnant. If you think you may be pregnant, please cancel your exam via MyChart
or by calling the patient scheduling office at 905-883-1212 ext. 2004 from Richmond Hill or 905-417-2000 ext. 2004 from Vaughan.
Please discuss the potential risks and options with your referring physician prior to your appointment. Your physician will examine your medical condition and decide on whether it is beneficial for you to have a nuclear medicine exam performed while pregnant.
- When you arrive for your exam, inform your technologist that you are pregnant. Your technologist will take precautions to decrease the radiation exposure to your baby
- If you are breastfeeding and are scheduled for a nuclear medicine scan you will need to stop breastfeeding for some time after the scan.
How do I prepare for a nuclear medicine scan?
You will receive a reminder notification a few days prior to your scheduled appointment. Please ensure you confirm or cancel through the automated system.
Arrival times vary depending on your appointment type. You will be advised by the Scheduling Office at the time of booking on your arrival time.
- Please follow any preparations provided when you schedule your appointment carefully as they can affect the accuracy of your scan results
- A reminder, Mackenzie Health is a scent-free environment
- Please do not wear any jewelry or other metal objects close to the area being scanned; you may be advised to change into a hospital gown.
Referring a patient
A completed Diagnostic Imaging requisition form must be completed by a physician’s office and can be faxed to 905-883-0772.
Please ensure the requisition form includes the referring physician’s information and signature, patient’s information and patient clinical history.
To obtain a copy of the general Diagnostic Imaging requisition form, visit the referral and consent forms page.
How do I find out my appointment date and time?
Please allow three to five business days for a completed requisition form to be reviewed and processed by Mackenzie Health.
A representative from Mackenzie Health Scheduling Office will call the you to advise:
- Appointment date, time and location
- Arrival time
- Associated preparation instructions for the test
If you receive a voicemail from the Scheduling Office, please call 905-883-1212 ext. 2004 from Richmond Hill or 905-417-2000 ext. 2004 from Vaughan to complete the pre-registration process.
You can also log in to MyChart to view appointment dates/times, confirm your upcoming appointments and complete the pre-registration process using the eCheck-In service.
How long does a nuclear medicine scan take?
Nuclear medicine scans vary in length depending on the type of scan. The scan itself can range between 15 minutes to 2 hours. Appointment duration varies depending on the type of test you are having. Some tests may require you to stay in the department up to 6 hours. Other tests may require you to return later on the same day or several days later for your scan. This is due to the time needed for the radioactive material to travel through the body.
How do I reschedule my appointment?
Please provide 48 hours’ notice if you need to cancel or reschedule your appointment. You can cancel your appointment online using MyChart but will need to reschedule by calling the Scheduling Office at 905-883-1212 ext. 2004 from Richmond Hill or 905-417-2000 ext. 2004 from Vaughan.
