A cardiac PET scan is one of the most effective forms of medical imaging because it not only provides images of your heart, but it also shows the specifics of how your heart is functioning. Patients receive PET scans because this advanced technology can help test for certain diseases, see how well different treatments are working, and assist in preparing for an upcoming surgery. 

What Technology Is Used In A PET Scan?

A cardiac PET scan is able to effectively show how your heart is functioning by using a radioactive tracer. This tracer is essentially glucose with a small radioactive component attached and may be injected, swallowed, or inhaled, depending on the area of focus in the body. The tracer’s radioactive technology is not harmful to you, but you should let your doctor know if you are diabetic, breastfeeding, or may be pregnant.

The PET scanner itself is a large ring-shaped machine that takes images of your body and picks up the radioactive waves of the tracer. In these images, different colors and degrees of brightness will show where in your body the tracer goes, indicating areas that may need to be examined closely for disease.

Why Is It So Effective?

With this technology, doctors can use the images to check blood flow to your heart muscles, decide treatment for clogged arteries, and analyze the effects of a heart attack. Cardiac PET scans are so effective because the technology can show problems at the cellular level, which gives your doctor the best view of complex diseases, such as heart disease. 

Cardiac PET scans are an effective option because the results are typically ready for your doctor to analyze within two business days, giving plenty of time for a course of action. To learn more about PET scans, contact Cardiac Imaging, Inc.

It can be alarming when your doctor recommends a PET scan, especially when you’re not exactly sure what this process entails. Cardiac PET imaging is used to understand how a person’s heart is functioning, and a doctor will recommend a PET scan when you are exhibiting certain symptoms and more information is needed to treat you and your heart.

Why Do You Need A PET Scan?

A PET scan uses radioactive tracers to measure the chemical reactions in your body in order to diagnose diseases. A doctor will recommend a cardiac PET scan to check the blood flow to your heart muscles. The scan can indicate areas of decreased blood flow, which allows your doctor to accurately decide the next steps. In addition to diagnosing diseases, cardiac PET imaging is also recommended to check if a specific treatment is working. If you get a PET scan, you might need a second to monitor your treatment plan.

How To Prepare

Your doctor will give you specific instructions before the PET scan begins in order to help you prepare. During this time, be sure to notify your doctor if you have certain allergies, if you are taking other medications or if you are claustrophobic. The week leading up to your scan you shouldn’t include strenuous physical activity. You should also avoid consuming food and beverages high in carbs and sugar in the last 24 hours before your scan.
