CARDIAC MRI
Overview
There are a whole bunch of non-invasive tests available that try to image the internal working of the different organs of a human body. Each of these tests has a specific aim and is suitable for certain type of diagnosis more than others. One of the popular and highly effective tests to image the different organs and their structures is Magnetic Resonance Imaging (MRI).
MRI can be used to create pictures with a very high degree of details for any part of the body. When this procedure is used to scan and create images of the heart and associated blood vessels, it is called Cardiac MRI. The Cardiac MRI procedure uses extremely strong magnetic fields and radiofrequency waves to create 2 dimensional and 3 dimensional images of the heart.
Since the Cardiac MRI test does not use any radiation as well as it is non-invasive, it is considered one of the safer tests, even during pregnancy although it is not advised in the first trimester. A highly effective procedure, the Cardiac MRI stress test helps your doctor to identify the following:-
- Heart Valve Defects
- Congenital Heart problems
- Extent of damage after a heart attack
- Heart failure symptoms
- Pericarditis
