What are the most common current applications of coronary MR angiography?
Coronary MR angiography has been, and remains, the most challenging area of cardiac MRI. Coronary arteries have a small diameter, may be extremely tortuous, and move rapidly due to both respiratory and cardiac motion. Currently, radiographic angiography remains the gold standard for evaluating coronary artery stenosis. The most common current applications of coronary MR angiography include the evaluation of anomalous coronary arteries and the assessment of bypass-graft patency. One of the earliest established indications for coronary MR angiography was the evaluation of anomalous coronary arteries.7 This condition has a prevalence of about 1.2%(Figure 3).7 Radiographic coronary angiography is limited in its ability to identify the anomalous vessels due to its projectional nature and is not used as screening tool in young adults. Coronary MR angiography has shown excellent results (93% to 100% of cases) in the identification and definition of anomalous coronary arteries. In addition, co
