Figure 1From: Quantification of aortic stiffness across the cardiac cycle using magnetic resonance elastography(a): Sagittal magnitude image with contour (red) outlining aorta. (b-e): Wave propagation at four points in time. (f, g): Weighted stiffness maps from x, y, and z encoding directions with a mean μMRE of 5.1 ± 1.4 kPa and 7.2 ± 1.6 kPa for end-diastole and end-systole respectively.Back to article page
