Magnetic resonance imaging (MRI) is a noninvasive medical test that physicians use to diagnose and treat medical conditions. MRI uses radio waves, magnets, and a computer to create pictures of your organs and tissues. Unlike other imaging tests, MRI doesn’t use ionizing radiation or carry any risk of causing cancer.
Cardiac MRI imaging is performed to help your physician detect or monitor cardiac disease by:
- Evaluating the anatomy and function of the heart chambers, valves, size and blood flow through major vessels, and surrounding structures such as the pericardium (the fluid filled sac that surrounds the heart).
- Diagnosing a variety of cardiovascular (heart and/or blood vessel) disorders such as tumors, infections, and inflammatory conditions.
- Evaluating the effects of coronary artery disease such as limited blood flow to the heart muscle and scarring within the heart muscle after a heart attack.
- Evaluating the anatomy of the heart and blood vessels in children and adults with congenital heart disease.
