What you need to know about PET and CT scans
[Body copy] A PET scan is a type of nuclear medicine that produces a three-dimensional (3D) image of how your body is functioning. It uses a small amount of radioactive material, called a tracer, that’s injected into your body before the scan. During the procedure, doctors measure changes specific to blood flow, how your body is absorbing the tracer material, and more.
CT shows your structure (anatomy), and the PET nuclear imaging shows metabolic processes, or chemical changes, happening within your body. This powerful combination allows us to accurately diagnose cancer and other medical conditions.
Atlantic Health System’s radiologists are board-certified experts in PET and CT scans. They all have advanced fellowship training in interpreting diagnostic imaging reports.
If you’ve never had a PET or CT exam before, you should know what to expect. Arriving prepared will ensure your visit goes smoothly.
How to prepare for a PET/CT scan
- You may be asked to wear a gown during the exam, or you may be allowed to wear your own clothing.
- Women should tell their physician and the PET/CT technologist if you are breastfeeding or if there is any chance you may be pregnant.
- Leave at home metal objects such as jewelry, eyeglasses, dentures and hairclips or remove them before your exam. You may be asked to remove hearing aids.
- After getting your tracer injection, you’ll need to relax for one to two hours before your scan. You may bring reading material if you decide to stay on-site during this time.
- To avoid delays, bring a written copy of the order provided by your doctor.
PET/CT scan results
A board-certified radiologist will closely examine and interpret your PET/CT images. They’ll send a signed report to your primary care physician or the doctor who referred you for the diagnostic imaging. Then your doctor will discuss the results with you.
PET/CT services may vary by location. Be sure to confirm the exact location of the medical imaging center when making the appointment.
