Diagnostic Imaging Department

Nuclear Medicine

What is Nuclear Medicine?
It is a medical imaging technology to view and analyze the function of different organs such as: bones, heart, kidneys, liver, lungs, thyroid, digestive system etc.
It is used for the detection of different disease to look at the progression or regression and sometimes treatment of some diseases.

The examination is called scintigraphy or scan. There is a small amount of a radioactive tracer (also called radioactive isotope) which is injected in a vein of the arm. For some procedures it is inhaled or ingested. There are different products for different organs.
The product will circulate in your body and will concentrate in the organ to be examined.
For some procedures imaging will start immediately after the injection, for others there will be a waiting period. The gamma radiation is coming from the organ and is detected by the gamma camera. The computer gives us an image which is analyzed by a nuclear medicine physician.

Before the exam
Inform the technologist if you are pregnant or breastfeeding

Preparation
The exam is painless.
There is no preparation for most exams.
You will be given instructions when we book the appointment.

The day of the exam
Report to the main entrance of the McConnell site, at 840 McConnell
You must stay still during the exam.
Remove all metal objects. Wear comfortable clothes.
The camera will be placed very close to you.
The camera may move slowly from head to toe or around the organ to be examined.
The time varies from 10 minutes to one hour for each visit.
The follow up visit are hours later or days later depending on the exam.

After the exam
The Nuclear medicine physician will analyze the images and a written report will be sent to the requesting physician and/or your doctor.
The radioactive product will naturally flush out of your system.
No after effects are expected you can resume normal activities.

(If you plan on going to the United States after the exam please request a note for the border agents from your technologist.)
