The major advantage of 3.0T whole-heart coronary MRA (CMRA) using a continuous gadolinium infusion is to combine lumenographic information and 3D myocardial viability in the same settings with patterns similar to those obtained by 2D-LGE (late Gd-enhanced) techinique. This suggests a potential of this technique to assist in recognizing the etiology of patients with left ventricular dysfunction (LVD) which is essential for the risk stratification and treatment selection.
