From: Visualizing regional myocardial oxygenation changes with statistically optimal colormaps
End-systolic adenosine images without (AD) and with LCX stenosis (SS) from the two controlled canine studies are shown in panels (A) and (B), respectively. The top row shows the AD and SS images without any windowing. The bottom row shows the same images but windowed the same to increase the regional myocardial contrast corresponding to oxygenation changes. Red arrows on the windowed SS images illustrate the limits of the affected myocardial segments corresponding to the LCX artery.
