Cardiac MR imaging is a non-invasive, radiation free technique to evaluate coronary artery disease, heart failure and congenital heart disease. It can help physicians to look closely at the structures and function of the heart and major vessels quickly without the risks associated with traditional procedures. Different cardiac MR tests can be performed such as Perfusion study, Dobutamine stress MR scan and Viability study. It can also diagnose cardiovascular problems such as aortic dissection and cardiac tumor.
