What is it ?
Magnetic resonance imaging (MRI) is the newest and most complex of the cardiovascular imaging modalities. Although MRI has been used for more than a decade to image the brain and other stationary organs within the body, only recently has it become widely available as a cardiovascular diagnostic approach In brief it is r MRI scanner optimized for imaging the moving heart.

MRI uses high intensity magnetic fields and radiofrequency to generate 3D/tomographic images with high resolution and excellent contrast. The blood's motion through the magnetic field can generate signal, obviating the need for contrast agents. The production of diagnostic quality angiograms of the coronary arteries with MRI (MR angiography [MRA]) is another area of rapid development and will likely become clinically important in the near future.
