PET/CT FAQ

How long will a PET/CT test take?

Approximately 3 hours. There is a 60 minute resting period before the test and the scan will take approximately 30 minutes to be performed.

What are the benefits of a PET/CT scan?

PET/CT replaces multiple medical tests with a single exam. It will often diagnose diseases before they would show up on other exams. A PET/CT scan can determine if a tumor is benign or cancerous and it can also show all of the organ systems to indicate whether or not cancer has spread. It shows the progress of disease and how the body responds to treatment.

Can I eat before a PET/CT scan?

No. Please do not eat anything 6 hours prior to your appointment. This includes candy, cough drops, breath mints, and chewing gum. You should also follow a low-carb diet one day prior to your scan.

Can I take my medications prior to the test? What if I have diabetes

Most medications are okay to take before a PET/CT. However, diabetic medicine must be taken no less than 6 hours prior to the test. Please let us know ahead of time if you are diabetic so we can make sure we find the safest way to prep for your PET/CT.
