Myocardial bridging of the left anterior descending artery displayed by volume rendering technique during diastole. Due to the intramyocardial course of the middle segment of the LAD, this particular segment is not imaged.
The curved planar reformatted CT angiogram shows minimal stenosis (arrow) of the LAD in the intramyocardial 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.
