What is a PET/CT Scan?
A PET/CT scan is a highly advanced medical imaging tool. Positron emission tomography (PET) shows your body’s metabolic activity, while the computed tomography (CT) shows your anatomy. When combined, the PET and CT scan shows what is happening inside your body, including both normal and abnormal metabolic activity, as well as the anatomic details of the area where the normal and abnormal activity is taking place.
A PET/CT scan is most often used to diagnose, detect, and localize a variety of common cancers and infections. PET/CT scans can also be used to assess neurological conditions and certain cardiac conditions.
The radiopharmaceutical that we use for PET/CT scans is ordered for each patient based on weight and time, so it is very important that you arrive on time for your scan. Should you need to cancel or reschedule your appointment, please call us at 401-444-7777.
If you are breastfeeding, pregnant, or think you may be pregnant, please call the PET/CT department prior to your appointment.
Please leave any personal belongings (jewelry, glasses, etc.) at home when having an outpatient exam performed at any of our facilities to avoid misplacement.

After Your PET/CT Scan
The radiopharmaceutical used in PET/CT is short-lived and should pose little risk of significant radiation exposure to your family and friends. However it is always good practice to minimize unnecessary radiation exposure to others, especially young children and pregnant women. Therefore, please follow these instructions for approximately eight hours after your scan:
- Avoid unnecessary prolonged contact with young children and pregnant women.
- Wash hands thoroughly after using the restroom.
- Drink plenty of fluids after your scan and empty your bladder frequently as this will help flush the remaining radioactivity from your body.
