What is a Cardiac PET Scan?
The cardiac PET scan, known medically as cardiac positron emission tomography is a noninvasive scan of your heart, using nuclear imaging. Radioactive tracers are used to produce images or pictures of your heart. These tracers mix in with your blood, which then flows through the heart and is able to be picked up with imaging technology. Different degrees of brightness and colors on the PET scan reveal different levels of heart tissue function.
Why You Might Need a Cardiac PET?
Your doctor may recommend you have a heat PET, in order to diagnose heart disease or a result of being diagnosed with abnormal heart rhythms. It’s also used to monitor the progression of coronary artery disease or to access the damage of a heart attack since the test details both healthy areas of the heart and damaged areas.
Physicians utilize the results of a cardiac PET to determine if you will benefit from cardio invention procedures, such as stenting, angioplasty, or coronary artery bypass surgery.
This type of cardiac scan can tell your physician if your heart is getting enough blood flow or if it is
reduced as a result of narrowed arteries. It can also show the cardiologist if there are dead cells from a previous heart attack.
Because the cardiac positron emission tomography is so accurate, it can help your doctor determined if you have any injured, but still viable heart muscle that could be saved when blood flow is restored.
What Happens During the Test?
Your technologist will place electrodes on various areas of your body, such as your legs, arms, and chest. You’ll also have an IV (intravenous live) placed in your arm, which is where the tracer is injected.
You’ll lie flat on a table that connected to a computer and the scanner. The table will slide in and out of a giant doughnut-shaped machine.
Several scans will be done to take multiple pictures of your heart, including from various angles. You’ll need to hold completely still while each scan is being performed. Once baseline images are taken, which can take up to 30 minutes. the tracer will be injected. Then, your heart will then be scanned again.
All-in-all, the test takes about one to three hours.
