Positron emission tomography (PET) scan is a diagnostic test that uses small amounts of radioactive chemical to show activity within the body on a cellular level. It helps doctors see how the organs and tissues inside your body are functioning. This test can be used to help diagnose or to evaluate how well a treatment is working.
PET scans are usually done to detect cancer, to evaluate the effectiveness of a cancer treatment therapy, to identify heart disease or a brain disorder. They measure blood flow, oxygen use, how your body uses sugar and much more. It is usually an outpatient procedure and takes about 2 hours.
PET scans can detect very early changes in your cells. CT scans and MRIs can only detect changes later, as a disease alters the structure of your organs or tissues. Sometimes a combination of two scans, CT and PET, is used to get a more well-rounded picture of the health issue.
If you are on a medical waitlist to get a PET scan and do not wish to wait, we can arrange it privately. Please note that those living in the Maritime provinces will need to travel outside their home province to get PET scan privately. Give us a call to find out more details. Toll free 1 877 344 3544.
