Abstract:
Objective To quantitate coronary tortuosity and provide favorable conditions for understanding the hemodynamic effects caused by coronary tortuosity.Methods We obtained all images from 72 patients who received coronary computed tomo-graphy scanning.After image post-processing,we extracted the medial axis of three main coronary vessel and analysed its coordi-nates on three dimensions.Then we calculated the tortuosity coefficient of coronary artery.Results Tortuosity coefficient was 6.66±7.54 in anterior descending,13.43±12.85 in left circumflex,and 1 7.61 ±7.67 in right coronary artery.We had proved its validity by the changes in morphology with simulated shapes.Conclusion We proposed a new method for quantitating coronary tor-tuosity,by computed tomography coronary imaging.The measurement results would not be affected by projection plane,vessel length or other artificial factors.
