Myocardial bridging of the left anterior descending artery displayed by volume rendering technique during diastole. Due to the intermyocardial course of the middle segment of LAD this particular segment is not imaged.
The curved planar reformatting CT angiography shows minimal stenosis (arrow) of LAD in the intermyocardial segment during late diastole (segment 760 ms). The stenosis increases during systole (segment 404 ms).
The oblique axial section during systole reveals the compressed segment.
