Figure 1

Representative cases for aortic magnitude images (A), aortic phase contrast images (B), aortic flow curves (C), and myocardial displacement magnitude images (D). The upper and bottom row respectively represents pre and post contrast agent data. Please note that no visual differences are found pre and post contrast agent administration in A-C. In A and B, the ROI delineating the aorta is indicated. In D, the lower image contrast between myocardium and blood pool and surrounding tissue post contrast agent administration is shown. Due to the lower image contrast, delineation of the left ventricular myocardium may be difficult post contrast agent administration. The left ventricular myocardial wall is delineated as performed by the automatic algorithm in the pre contrast agent image. The delineation has been copied onto the post contrast agent image for comparison. CA = contrast agent; LV = left ventricle; RV = right ventricle.
