What Is a PET/CT Scan?
A PET/CT scan merges two imaging technologies:
- Positron Emission Tomography (PET), which shows how tissues and organs function at the cellular level
- Computed Tomography (CT), which provides detailed images of internal structures
Together, these scans create highly detailed images that help identify abnormalities with greater accuracy than either test alone.
PET/CT scans are commonly used in oncology, cardiology, and neurology.

Frequently Asked Questions
-
A PET/CT scan requires a physician referral. Your care team will coordinate scheduling and provide preparation instructions.
-
A PET/CT scan appointment can take around two hours in total, including preparation time. The scan itself takes 25 to 45 minutes, depending on the body part imaged and the purpose of the scan.

-
Wear comfortable, loose-fitting clothes you can easily move in. Dress warmly in layers for comfort. Because metal interferes with the images, do not wear any jewelry or metal accessories.
-
For most PET/CT scans, especially those related to cancer detection, patients are advised to follow a low-carbohydrate, high-protein diet for 24 hours before the scan and to fast for 6 hours before the procedure. This helps ensure accurate imaging by minimizing blood sugar levels and optimizing tracer uptake. Important: Always follow specific instructions given by your doctor or imaging center, especially if you are diabetic or on medication, as fasting guidelines may vary.
-
In most cases, yes, you can drive after a PET/CT scan, especially if you were not given any sedatives. The radioactive tracer used during the scan has no sedative effect and leaves the body naturally through urine over the next few hours.
However, you should not drive if:
- You received sedation or medication to help you relax.
- You feel lightheaded or tired after the procedure.
If you're unsure, bring someone to drive you home, especially for your first scan or if sedation is involved.
-
You will get your results in 24 to 72 hours. The fastest and easiest way to see your results is through the PineApp. Baptist Health’s app helps you easily manage your healthcare — including viewing PET/CT scan results — from any mobile device.
-
Yes, a PET/CT scan uses a radioactive tracer to highlight key areas and their function. However, the amount of radioactivity is low, and the benefits of the scan can positively inform your care.
-
You may experience brief discomfort when placing the IV for the tracer. The actual PET/CT scan is painless and noninvasive. While you lie comfortably on a table, it moves you into the PET/CT ring.
