Cardiac MRI

Another technique called magnetic resonance imagingA technique for imaging the body that uses electromagnetic waves and a strong magnetic field. (MRIAn abbreviation for magnetic resonance imaging, a technique for imaging the body that uses electromagnetic waves and a strong magnetic field.) may be used to get images that give information about the structure and function of the heart, using high-contrast resolution, and without using any ionising radiation.[1,2]

Cardiac MRIAn abbreviation for magnetic resonance imaging, a technique for imaging the body that uses electromagnetic waves and a strong magnetic field. can be employed in people who have had a heart attackThe death of a section of heart muscle caused by an interruption in its blood supply. Also called a myocardial infarction. to assess how much working, healthy heart muscleTissue made up of cells that can contract to bring about movement. there is, the overall function of the heart or the function of parts of the heart, and the size of the damaged area of heart muscleTissue made up of cells that can contract to bring about movement..[1]
