Positron emission tomography, also called PET imaging or a PET scan, is one of the most advanced diagnostic exams. PET scans find tumors and measure blood flow. PET scans also locate suspected abnormal growths as well as growths that might have spread in the body.
A PET scan is useful in identifying several conditions including:
- Brain disorders
- Heart disease
- Monitoring the effects of cancer therapy
Modern PET scanners are paired with a CT scanner. The two technologies use sophisticated computer systems to evaluate both the structure and function of the body.
How Does a PET Scan Work
PET scans use a radioactive tracer to show how your tissues and organs are functioning. The tracer may be injected, swallowed or inhaled, depending on the area of your body being examined. You lie on your back with your arms to your side. The automatic bed moves while the scan takes place, usually starting with your head and moving to your lower body. The test can take between five and 40 minutes depending on the type of PET scan.
Preparing for Your PET Scan
Before your exam, you may be required to fast for four hours. The day before your scan, you will receive instructions specific to your scan.
Please arrive 15 minutes before your exam time. Remember to bring a photo ID, your insurance card, medication lists and any additional forms provided by your doctor.
