Myocardial Perfusion Imaging (MPI)
Myocardial perfusion imaging, or MPI, is a noninvasive imaging test that shows how well blood flows through, or perfuses, the heart muscle. MPI can show areas of the heart muscle that aren't getting enough blood flow, and how well the heart muscle is pumping. This is sometimes referred to as a nuclear stress test or a thallium stress test.
Computed tomography, or CT, scans use a series of x-rays and computer analysis to create detailed and cross-sectional images of internal organs and structures. A cardiac CT can provide pictures of the beating heart, and show calcium and blockages in the heart arteries. This imaging study is sometimes called a virtual angiogram.
Magnetic resonance imaging, or MRI, uses a powerful magnet and radio waves to create images of internal organs and structures. A cardiac MRI can provide detailed information on the type and severity of heart disease.
A chest x-ray takes pictures of the organs and structures inside the chest, such as the heart, lungs, and blood vessels. This imaging test can reveal signs of heart failure, as well as lung disorders and other causes of symptoms not related to coronary artery disease, or CAD.
Blood tests may be done to check the levels of certain fats, cholesterol, sugar, and proteins in the blood. Abnormal levels may be a sign of risk for coronary artery disease, or CAD.
