Figure 5 (Top left) Dataset that contains the mid portion of the left ventricle, obtained using transthoracic imaging in a pig (anteroseptal region [asp] of interest shown in yellow). Example of en-face short-axis views of a mid-papillary three-dimensional slice obtained at baseline (middle row) and during partial left anterior descending artery occlusion (bottom row) before the onset of (left) and during (center) myocardial contrast inflow, and (right) after reinstatement of steady-state contrast enhancement. (Top right) Regional myocardial video-intensity (MVI) curves obtained in the mid-papillary anteroseptal region of interest: baseline (green) and partial left anterior descending artery occlusion (red). PCIR = peak contrast inflow rate.
