What is PET Scan? Know everything about PET Scan

PET scan, also known as positron emission tomography, is a procedure used to find early signs of cancer, cardiovascular, brain disorders, and cancer cells in the body. 


While performing a PET scan, the patient lies on a table that slides through the PET machine. The headrest and white strap help the patient lie still. A small amount of radioactive glucose (sugar) is injected into the patient’s vein, and a scanner makes a picture of where the glucose is being used in the body. Cancer cells show up brighter in the picture because they take up more glucose than normal cells do.

Why do healthcare providers use PET scans?

The healthcare provider may recommend a PET scan to check for signs of:

  1. Cancer, including breast cancer, lung cancer, etc.
  2. Brain disorders, such as brain tumors, epilepsy, dementia, and Alzheimer’s disease.
  3. Coronary artery disease, heart attack, or other heart disorders.

What does a PET scan show?

A PET scan can:

  1. Detect cancerous tumor cells to help gauge cancer spread (metastasis).
  2. Measure vital functions, such as blood flow, oxygen use, and blood sugar (glucose) metabolism.
  3. Evaluate how well a treatment plan is working and help your healthcare provider adjust treatment if needed.
  4. Identify organs and tissues that aren’t working as they should.

How should you prepare for a PET scan?

To get tested for PET scan, you should:

  1. Don’t eat anything before 6 hours of a PET scan. If you’re diabetic, you can contact your doctor for this.
  2. Don’t consume caffeine or its products before the test.
  3. Drink water only.
  4. Wear comfortable clothes.
  5. Inform your doctor about the medicines you are taking during the PET scan.

What is the duration of the PET scan?

The entire process of a PET scan takes about 2 hours. It can take up to 60 minutes for your body to absorb the injected radiotracer. During this time, you’ll need to sit quietly and limit your movements. The actual PET scan takes about 45 minutes. After the test, you’ll need to wait while the technologist reviews the scans to ensure the images are clear.

When should you get the results?

A radiologist with specialized training in PET scans will review the images, write a report and send it to your healthcare provider. This process usually takes 2-4 hours.
