  At present, coronary angiography is the well known standard for the diagnosis
of coronary artery disease. Conventional coronary angiography is an invasive
procedure with a small, yet inherent risk of myocardial infarction, stroke,
potential arrhythmias, and death. Other noninvasive diagnostic tools, such as
electrocardiography, echocardiography, and nuclear imaging are now widely
available but are limited by their inability to directly visualize and quantify
coronary artery stenoses and predict the stability of plaques. Coronary
magnetic resonance angiography (MRA) is a technique that allows visualization
of the coronary arteries by noninvasive means; however, it has not yet reached
a stage where it can be used in routine clinical practice. Although coronary
MRA is a potentially useful diagnostic tool, it has limitations. Further
research should focus on improving the diagnostic resolution and accuracy of
coronary MRA. This paper will helps to cardiologists to take the clear look of
spatial filtered imaging of coronary arteries.
