Magnetic resonance imaging (MRI) is a medical imaging technique used to produce detailed images of the organs and tissues within the body. Cardiac MRI is a specialized type of MRI that is specifically designed to produce high-quality images of the heart and surrounding blood vessels.
During a cardiac MRI, a person lies on a table that slides into a large, tunnel-like machine. The machine contains a powerful magnet and radio waves, which are used to produce the images. The person is asked to remain still and may be given a contrast agent to help improve the clarity of the images.
Cardiac MRI is used to evaluate the structure and function of the heart, as well as the surrounding blood vessels. It can be used to diagnose a variety of heart conditions, including coronary artery disease, heart attacks, and abnormalities in the heart’s structure. Cardiac MRI is also used to assess the effectiveness of certain treatments, such as bypass surgery or angioplasty.
The cost of a cardiac MRI can vary depending on the specific procedure and the location where it is performed. In general, MRI procedures are more expensive than other imaging techniques, such as X-rays or CT scans.
Cardiac MRI is typically ordered by a doctor or other healthcare provider, such as a cardiologist. It may be recommended for people who have symptoms of a heart condition, such as chest pain or shortness of breath, or for those who are at high risk of developing heart disease.
Examples of diseases that may be diagnosed using cardiac MRI include:
- Coronary artery disease
- Heart attacks
- Heart failure
- Heart valve problems
- Cardiomyopathy (disease of the heart muscle)
