Cardiovascular MRI is a non-invasive test used to evaluate the structure and function of the heart and blood vessels. Because it uses large magnets and radio-frequency waves instead of x-rays to produce high quality still and moving pictures of the body’s internal structures, patients are not exposed to potentially harmful radiation. A cardiovascular MRI also allows physicians to obtain images of larger areas – such as the chest and entire cardiovascular system – from many angles. Your physician may recommend this test to provide information about the cardiovascular system that cannot be obtained with other tests.

During a cardiovascular MRI, patients are positioned on a moveable exam table. In some cases, straps and bolsters may be used to help patients lie completely still during the procedure. If a contrast material is used, a health professional will insert it through an intravenous (IV) line. This material helps physicians identify irregularities in the heart and surrounding vessels. Most cardiovascular MRI exams last no more than 20 minutes and are painless. A mild sedative may be given to patients who experience anxiety caused by small spaces or have difficulty remaining still during the procedure.
