Virtual autopsy is a new technique for investigating the morphological changes of cadaveric tissues and organs by medical imaging technology. It has been widely used in the identification of causes of death. Multislice spiral computed tomography （MSCT） has become a routine inspection method in some identification institutions, although it cannot completely replace traditional autopsy, it plays a key auxiliary or substitute role in the identification of certain abnormal causes of death. Plain MSCT scan cannot visualize cadaveric vessels, but can perform cadaveric angiography to determine vascular injury or disease. This technology has entered a rapid development period in recent years, and has made a considerable progress in contrast agent, perfusion methods and imaging methods. This article summarizes several common cadaveric MSCT angiography methods, such as systemic angiography, angiography through cardiopulmonary resuscitation, targeted angiography, and angiography by cardiac puncture, and analyzes and compares the application prospects.
题目: 尸体MSCT血管造影技术的法医学研究现状.
摘要: 虚拟解剖是应用医学影像学技术探究尸体组织器官形态学改变的一门新技术，目前其在死因鉴定中的应用日趋广泛。某些鉴定机构已将尸体多层螺旋计算机断层扫描（multislice spiral computed tomography，MSCT）作为常规检查手段，虽然其尚不能完全替代传统尸体解剖，但在某些非正常死亡的鉴定中可起到关键辅助或替代作用。MSCT平扫无法对尸体脉管系统进行成像，但可以进行尸体血管造影来判断血管损伤或者疾病。近年来，该技术进入了快速发展阶段，在对比剂、灌注方法以及成像方法上都有较大进展。本文综述了常见的几种尸体MSCT血管造影技术，包括全身造影、心肺复苏技术造影、靶向造影和心腔穿刺造影等，并对其应用前景进行分析比对。.
