Pet Scan

Nuclear Cardiology is a valuable tool cardiologists use to diagnose coronary artery disease, still the number one killer of men and women in the United States each year.

We are always trying to improve our ability to detect this disease process, and be more selective about who we feel needs an invasive cardiac catherization.

The PET Scan is considered the most sensitive way to make this diagnosis non-invasively. Across most research studies, the Pet Scan is over 90-percent accurate in detection of coronary artery disease.

The advantages of a PET Scan are many:

1. Much shorter testing time for both rest and stress testing-- about one hour.
2. A radioisotope that lasts about 75 seconds in one’s body versus conventional isotopes that last hours to days. This short exposure leads up to 2/3 less radiation.
3. The ability to not only detect coronary artery disease, but also give risk data that helps guide proper treatment.

Baker-Gilmour is the only cardiology practice in Jacksonville to offer this most accurate and sophisticated diagnostic equipment in its office.


Who should have a PET Scan?

Your doctor may order a PET Scan by following the guidelines established by the American College of Cardiology, American Society of Nuclear Cardiology and the American Heart Association that include the following;

1. Patients who cannot adequately exercise on a treadmill
2. Patients with certain abnormal resting EKG
3. Women
4. Larger patients with a body mass index (BMI) of 35 or over

Pet Scan Patient

What to expect when you have a PET Scan?

1. You will be asked to fast and have no caffeine for at least twelve hours before the procedure.
2. You will lie down on a movable table and an intravenous line (IV) will be started in your arm. The tests will involve both a “rest” and “stress” portion.
3. A radioisotope will be injected into the IV. The “resting” pictures will be taken by a camera that does not enclose you. This will take about five to six minutes to complete.
4. The “stress” portion of the test will begin with an injection of a medicine (Lexiscan) that simulates exercise.
5. After several minutes another injection of the same radioisotopes as the “rest” portion will be injected and pictures will be taken. Again, this too should last another five to six minutes.
6. From “hello” to the “goodbye,” and everything in between will be approximately one hour.
