3D architecture of myocardial microcirculation in intact rat heart: a study with micro-CT.
The branching geometry of the coronary arterial tree may play a significant role in the observed spatial heterogeneity in myocardial perfusion. To provide more insight into this possibility we used a micro-CT scanner to image the intact rat heart and its opacified coronary arterial tree, for quantitative analysis of the coronary arterial architecture. Results show a consistent pattern of branching throughout the heart wall.
