Three-dimensional (3D) reconstruction images using postmortem computed tomography (PMCT) are increasingly used to convey complex information to non-medical professionals, such as police and jurors. This case report demonstrates the effective use of 3D reconstruction images by integrating pre-autopsy, intra-autopsy, and knife CT data to achieve precise visualization of the wound path and associated injuries. The case involved a man in his 40s who was stabbed multiple times and pronounced dead approximately two hours after receiving emergency treatment. Initial PMCT revealed an intraperitoneal hemorrhage; however, no injuries to the abdominal organs or aorta were identified. During the autopsy, a critical abdominal aortic injury was discovered, prompting a further CT scan; however, the aorta remained in situ. By utilizing pre-autopsy, intra-autopsy, and knife CT data, the spatial relationships between the stab wound in the right hypochondriac area, aortic injury, and knife were effectively visualized. This novel approach highlights the potential of intra-autopsy CT for precise forensic visualization, offering a strategy for improvements in the accuracy and clarity of forensic evidence presentation.
利用尸检后计算机断层扫描（PMCT）生成的三维（3D）重建图像越来越多地用于向警察和陪审员等非医学专业人员传达复杂信息。本病例报告展示了通过整合尸检前、尸检中和刀具CT数据有效使用3D重建图像，以实现对伤口路径及相关损伤的精确可视化。该病例涉及一名40多岁的男子，他被多次刺伤，在接受紧急治疗后约两小时被宣告死亡。最初的PMCT显示腹腔内出血；然而，未发现腹部器官或主动脉有损伤。尸检过程中，发现了一处关键的腹主动脉损伤，促使进行进一步的CT扫描；然而，主动脉仍在原位。通过利用尸检前、尸检中和刀具CT数据，有效可视化了右季肋区刺伤、主动脉损伤和刀具之间的空间关系。这种新方法突出了尸检中CT在精确法医可视化方面的潜力，为提高法医证据呈现的准确性和清晰度提供了一种策略。
