Figure 1From: A quantitative comparison of regional myocardial motion in mice, rabbits and humans using in-vivo phase contrast CMRPixel-by-pixel vector field plots and color-coded maps of radial velocities of in-plane velocities (red: contraction, blue: expansion) in a basal slice for four characteristic cardiac frames. Note the different rotational behavior during early systole in the vector field plots for the mouse compared to the human subject and the rabbit. The yellow arrows are included for better visualization of the vector field and are determined by averaging the pixel-wise vectors within each of eight myocardial regions.Back to article page
