PMCT在机械性窒息方面的研究进展

机械性窒息是公安法医日常检案中最常见的死因之一。如何快速准确的判断死者是否为机械性窒息死亡、以及作案手段是判断案件性质、指引案件侦破方向的重要因素。在法医鉴定过程中,诊断机械性窒息需要结合尸体体表征象、尸体内部征象、组织病理学检验等多方面综合判断。PMCT在骨折的检测、异物的检测和气体的检测方面具有极大的优势,在许多国家和地区已作为常规检验手段。本文综述了国内外近年来使用PMCT研究机械性窒息案例中舌骨骨折、甲状软骨骨折、椎间盘真空现象等多个征象的成果,讨论了PMCT诊断机械性窒息的应用价值与潜力,并对国内PMCT的发展前景进行了展望。

Research progress of PMCT in mechanical asphyxia

Mechanical asphyxia is one of the most common causes of death in forensic cases. How to quickly and accurately determine whether the death is caused by asphyxiation and what causes it is an important factor to judge the nature of the case and guide the direction of the case investigation.In the process of forensic examination, the diagnosis of mechanical asphyxia requires the combination of body surface signs, internal signs of the corpse, histopathological examination and other aspects. PMCT has great advantages in fracture detection, foreign body detection and gas detection, and has been routinely used in many countries and regions.This paper reviews the research results of hyoid bone fracture, thyroid cartilage fracture, intervertebral disc vacuum phenomenon in mechanical asphyxia cases using PMCT in recent years. the application value and potential of PMCT in diagnosis of mechanical asphyxia are discussed, and the necessity and prospect of the development of PMCT in China are prospected.
