PET-CT

PET-CT is a special imaging test that combines two types of scans: Positron Emission Tomography (PET) and Computed Tomography (CT). This test helps providers see inside your body and find problems like cancer, heart disease, or brain disorders. The combination of these two scans produces detailed and accurate images.

During a PET-CT scan, you will receive a small amount of radioactive material through an injection. This material helps highlight areas of your body that are not working properly. The CT scan takes pictures of your body, while the PET scan shows how your organs and tissues are functioning.

The whole process usually takes about 30 to 60 minutes. You may need to lie still during the scan, but it is not painful.

A PET-CT scan is used to help doctors:

• Find cancer and check how well cancer treatments are working.
• Look at heart disease and how well your heart is functioning.
• Examine brain problems like Alzheimer’s disease or seizures.

Your doctor will explain why you need the scan and how it will help in your treatment plan.

Here is what you can expect during a PET-CT scan:

1. Preparation: You may be asked to avoid eating or drinking for a few hours before the test.
2. Injection: A small amount of radioactive material will be injected into your vein.
3. Resting: You will wait for a short time while the material moves through your body.
4. The Scan: You will lie on a table, and the PET-CT machine will take images of your body.
5. After the Scan: There are no special instructions after the test, and you can return to your usual activities.

PET-CT is a safe procedure. The amount of radiation used in the scan is very small, and the benefits of having the scan usually outweigh any risks. Your doctor will discuss any concerns you may have before the test.

• Follow your doctor’s instructions: You may need to avoid eating for a few hours before the test.
• Wear comfortable clothes: You may be asked to change into a hospital gown for the scan.
• Let your doctor know about any medications: Some medications can affect the test results.
