【摘要】 目的对不同类型案件中的死者进行死后尸体CT扫描和常规尸体解剖,探索PMCT在法医学鉴定中的应用价值。方法对7例因不同原因死亡的个体进行全身PMCT扫描,随后进行系统的尸体解剖,通过比较两种方法检测的结果,分析PMCT与传统尸体解剖在不同类型案件中应用的优点和不足。结果在7个案例中,尸体上总共检出67处阳性发现。其中,尸体解剖发现50处阳性结果(检出率74.63%),PMCT发现62处阳性结果(检出率92.54%)。此外,PMCT对骨骼损伤、软组织损伤以及体内金属异物的检出率高于传统尸体解剖,但在对尸体血管病变的检测中,常规PMCT的检测效果不如尸体解剖。结论在法医学鉴定实践中,联合应用PMCT和尸体解剖技术有助于发现更多的阳性结果,能够提高法医病理学诊断的质量。更多还原

【Abstract】 Objective The purpose of this comparative study was to evaluate the application value of postmortem computed tomography(PMCT) in forensic autopsy. Methods Whole body PMCT was performed on 7 decedents died from different causes and followed by systematic autopsy. Findings from the two examinations were compared to reveal the advantages and disadvantages of PMCT and autopsy in different types of cases. Results Among 67 positive findings,autopsies helped to identify 50(74.63%) and PMCT helped to identify 62(92.54%). In addition, PMCT scan showed a higher positive detection rate than autopsy in examination of bone injury, soft tissue injury and residual metal foreign bodies in vivo. However, the detection effect of vascular lesions based on PMCT was not as good as autopsy. Conclusion More positive findings can be detected by combining PMCT and autopsy in forensic practice, which may improve the quality of forensic pathological diagnosis.更多还原
