PET/CT scan

What is a PET/CT scan?

A PET/CT scan is a combination of a PET and CT scan in one machine. A CT scan generate an image of tissue structures through x-rays, while a PET scan offers information about metabolic processes within tissue. Using a PET/CT scan, we can examine the nature and location of the abnormality in great detail. A PET/CT scan can also help us see whether radiation therapy or chemotherapy has been effective for patients who have been previously diagnosed with cancer.

FDG PET/CT scan 

Cancer cells and infections require a lot of energy in the form of sugars (glucose). We can use a PET/CT scan to map out where the glucose in your body is metabolized  to locate any potential tumors. We will administer a small dose of radioactive glucose (FDG), after which you will need to rest for an hour in a special room. After that we can make the scan. 

The small dose of radioactive substance will not cause damage and will leave the body through urination. Please drink a liter of water before coming in for the procedure, and make sure you have not eaten anything for at least 6 hours before your appointment.


This procedure will take 1 hour and 45 minutes.

After the procedure

You can go home directly after the procedure. Please keep in mind that you cannot bike or drive after taking a valium.


Your physician will discuss the results with you during your next consultation.
