PET/CT Scan Q & A

What is a PET/CT scan?

PET (positron emission tomography) is a diagnostic imaging test that provides information about your physiological function by using radioactive drugs to monitor your blood flow, metabolism, and neurotransmitter activity. 

PET scans show where the radioactive material is absorbed in your body. These images are combined with a CT (computer-aided tomography) scan to create a detailed picture of the structure and function of your organs and other body parts. 

Why would I need a PET/CT scan?

The radiologists at Sun Radiology use PET/CT scans to identify and monitor a wide range of diseases, including:

  • Cancer
  • Alzheimer’s
  • Dementia 
  • Heart diseases 
  • Brain disorders 
  • Memory disorders 

In addition to diagnosing health problems, the team at Sun Radiology also uses PET/CT scans to monitor the progression of cancers, heart diseases, and dementia as well as to check whether the treatment has been effective. 

How should I prepare for a PET/CT scan?

Sun Radiology provides detailed instructions on how to prepare for your PET/CT scan. For example, you must not consume any carbohydrates or sugars for 24 hours before your appointment. 

In addition, you can only drink water for six hours before the exam. You must also avoid strenuous physical activity for 24 hours. 

You must arrive on time for your PET/CT scan as you’ll need a certain amount of time for the radiotracer to move through your body before the scanning process begins.

What happens during a PET/CT scan?

Your radiologist provides the radioactive material through an injection, and you need to rest quietly for up to 45 minutes as the drug moves through your body. 

Then, you lie on a narrow treatment table that glides slowly through the PET/CT scanner, which resembles a giant doughnut. 

You need to stay still throughout the scan, which can take up to two hours depending on the area being scanned. While the scan itself is painless, you may find it uncomfortable to stay still for such a long time. 

You can return to your regular activities as soon as your scan is over. Drink plenty of water to help flush the radioactive material out of your body and stay away from pregnant women and infants.
