Study Summary
Blood flows to areas of the heart providing oxygen and fuel to the pumping muscle. Occasionally the arteries providing the fuel can become blocked. This occurs in coronary artery disease. Magnetic resonance imaging (MRI) can be used to evaluate the blood flow to different areas of the heart muscle. In this study magnetic resonance imaging will be compared to other diagnostic tests (radionucleotide perfusion studies) capable of measuring blood flow to heart muscle.
