摘　　要：利用虚拟解剖技术可以提供个体的损伤或死后变化的二维或三维影像信息,利用这些信息可以为法医学实践提供直观、有力的科学证据。在缢死鉴定中,死后CT(post-mortem CT,PMCT)检见的气体征象可用于死亡原因和死亡方式鉴定。本文综述了颈部、纵膈和椎间盘部位的气体征象,讨论了颈部气泡征象、颈部皮下气肿、纵膈气肿和椎间盘真空征的影像学表现、形成机制与法医学意义。为虚拟解剖在缢死法医学鉴定中的应用提供借鉴。Two-dimensional or three-dimensional image information of individual injury or postmortem changes can be provided by virtopsy, which is intuitive and powerful scientific evidence in forensic practice. In investigation of death by hanging, air phenomenon detected by PMCT can certain cause and manner of death. We reviewed the air phenomenon in neck, mediastinum and intervertebral disc, and discussed gas bubble sign, subcutaneous emphysema, mediastinal emphysema, and vacuum phenomenon of intervertebral disc. It provides reference for the application of virtopsy in hanging cases.
