Fig. 2 —Reformatted left main and left anterior descending coronary MR angiography obtained in four volunteers using conventional navigator-guided coronary artery imaging technique (NAV), NAV + k-space weighted motion-adapted gating (k-MAG), NAV + sensitivity encoding (SENSE), and NAV+SENSE+k-MAG (from left to right). Notice slight increase in noise in two right-most images due to incorporation of SENSE. Curved black protrusions into right ventricular outflow tract seen on images in row 3 and row 4 are due to "flattening" effect of displaying curvilinear reformation of left main and left anterior descending coronary artery as single image.
