摘　　要：目的 探索基于虚拟解剖的尸体计算机断层扫描肝脏三维切片(three dimensional slicer,3D slicer)人工智能(Artificial Intelligence,AI)体积重建辅助法医实践的应用效果。方法 选取本中心20例同时进行虚拟解剖及传统尸检的死者,对其进行3D slicer法、多田公式法、文献法进行肝脏体积分割,并与传统尸检所得数据进行对比分析,得出准确率。结果 与多田公式法及文献中提及的方法相比,3D slicer法得到了更高的一致性(95%置信区间)、更低的体积变异性(标准差)以及较小的不确定区域(方差齐)。结论 基于虚拟解剖的3D slicer AI重建可以对虚拟解剖进行可视化,有助于增加传统尸检诊断准确率,辅助进行病理诊断,并对虚拟解剖的影像组学发展提供新方向、新手段。Objective To explore the effectiveness of virtual autopsy-based postmortem computed tomography(PMCT)liver three dimensional slicer(3D slicer)artificial intelligence(AI)volume reconstruction to assist forensic practice.Methods Twenty cases of the deceased who underwent both virtual autopsy and traditional autopsy in our center were selected and subjected to liver volume segmentation by 3D slicer method,Tada's formula method and literature method,and the data obtained from the traditional autopsy were compared and analyzed to obtain the accuracy rate.Results The 3D slicer method yielded higher consistency(95%confidence interval),lower volumetric variability(standard deviation),and a smaller region(variance)of uncertainty than the Tada formula method and the methods mentioned in the literature.Conclusion 3D slicer AI reconstruction based on virtual autopsy can visualize virtual anatomy,help increase the diagnostic accuracy of traditional autopsy,assist in pathological diagnosis,and provide new directions and tools for the development of imaging histology of virtual autopsy.
