64层螺旋CT在先天性心脏病中的临床应用

迅速发展的64层螺旋CT增加了扫描速度,提高了空间分辨率,实现心血管及肺实质同时评价的功能,在先天性心脏病方面得到一定的应用,在心电门控条件下,CT图像可以准确地描绘心脏的运动、心旁结构,同时了解有无冠状动脉粥样硬化性心脏病,以及有无冠状动脉的起源异常,另外64层螺旋CT可以通过室壁运动来评估心功能,或者心脏瓣膜,具有以上这些优点,使它在先天性心脏病诊断与治疗中起到重要的作用,本文主要介绍64层螺旋CT在先天性心脏病中的临床应用,特别是在术前与术后的评估作用。

Clinical Application of 64-Slioe CT in Congenital Heart Disease

The development of 64-section CT, with increased scanning speed, higher spatial resolution, and enhanced capabilities for simultaneous evaluation of cardiovascular structures and lung parenchyma, has increased the clinical application of CT for the evaluation of patients with congenital heart diseases, When coupled with electrocardiographic （ECG） data, CT images accurately delineate rapidly moving cardiac and paracardiac structures and allow an assessment of coronary artery disease and associated coronary artery a- nomalies. In addition,64-section CT may be used to obtain functional data about motion of the ventricular wall or cardiac valves. The modality should play a particularly substantial role in the evaluation of patients af- ter surgical intervention for congenital heart disease, This article introduced clinical appplication of 64-Slice CT in congenital heart disease, specially in the preoperative and postoperative.
