A PET scan can accurately diagnose coronary artery disease and detect areas of low blood flow in the heart. PET can also identify dead tissue and injured tissue that’s still living and functioning. If the tissue is viable, you may benefit from a PCI or coronary artery bypass surgery.
It can show areas of the heart muscle that aren’t getting enough blood flow. It can also show how well the heart muscle is pumping. This test is often called a nuclear stress test. There are two types of MPI: single photon emission computed tomography (SPECT) and positron emission tomography (PET).

A CCTA scan is used to help find the presence of and percent of narrowing (stenosis) in the coronary arteries and blood vessels that supply blood to the heart or other parts of the body. Multidetector CT, or MDCT, scans work fast and are very detailed.
A cardiac MRI is a noninvasive test that uses a magnetic field and radiofrequency waves to create detailed pictures of your heart and arteries.
A CAC test, also called a heart scan, is a CT scan of your heart done with a multidetector CT (MDCT) that takes detailed images of the arteries that supply blood to the heart muscle. The images show calcium deposits you may have in your coronary arteries.
Transesophageal echocardiography (TEE) is a test that produces pictures of your heart. TEE uses high-frequency sound waves (ultrasound) to make detailed pictures of your heart and the arteries that lead to and from it.
A SPECT scan of the heart is a noninvasive nuclear imaging test. It uses radioactive tracers that are injected into the blood to produce pictures of your heart. Doctors use SPECT to diagnose coronary artery disease and find out if a heart attack has occurred.
Radionuclide ventriculography or radionuclide angiography is often referred to as a MUGA (multiple-gated acquisition) scan. It’s a type of nuclear imaging test. This scan measures your ejection fraction, which shows how well your heart is functioning.
A CT scan creates images of the valve anatomy and allows for evaluation of the severity of stenosis and regurgitation. A CT scan also can determine whether there are valvular lesions or nearby tumors affecting the function. Read more about CT scans.
