What is a PET/CT scan and how does it work?What is a PET/CT scan and how does it work?

PET stands for Positron Emission Tomography and CT is short for Computed Tomography. A PET/CT scan collects information on how your tissues and organs are currently working. This information can be used to locate, diagnose, and monitor many health issues including cancer. The scanner equipment looks like a standard CT machine.

During a PET/CT scan, a small amount of radioactive material called radiotracers, or radiopharmaceuticals, are injected into a vein in your arm or hand. These radiotracers help the PET/CT scanner detect where issues may be located and help determine the best treatment possible. PET/CT scans give your health professional information not available from other types of scans.

What is the scan used for?What is the scan used for?

PET/CT scans are used to help in the diagnoses of brain and neurological conditions. These may include tumours, dementia, Alzheimer’s disease, or similar conditions.

Scans are also used to locate cancer in order to determine the best treatment possible while also monitoring existing treatments. It can also help your health professional plan for surgery or radiation therapy.

In some instances, PET/CT scans can also be used to diagnose heart-related issues such as coronary artery disease.

Will I need to fast before my scan?

As pre-scan preparations will vary by the scan needed, please check with us when making your appointment or with your consulting doctor.

Do I need to be accompanied by a family member for my scan?

PET/CT scans are non-invasive and painless procedures that typically do not require a support person to attend the appointment with you. However, if you do require sedation for your scan, you will need to be accompanied by a family member for your safety.

Are PET/CT scans safe?

The small amounts of radiation that you will be exposed to during these scans have not been shown to cause harm. However, for children or patients that require multiple PET/CT scans there may be a slight increase in the risk of cancer in the future.

If you are concerned, please with your doctor about your personal health history and the number of scans you have had previously. This will help them decide the safest option for you.
