摘　　要：目的 探讨64层螺旋CT在道路交通事故全身尸体检验中的应用价值.方法 根据事故现场监控录像、现场勘查照片等获得本例行人道路交通事故的发生过程.由专业的法医于事故当天对遇难者尸体进行尸表检验,得出尸体检验报告.采用64层螺旋CT对遇难者尸体进行全身扫描,并在后处理工作站对CT断面图像进行多平面重建和三维重建.将CT图像所见与尸体检验报告进行比较.结果 尸表检验发现遇难者全身多处软组织损伤、蛛网膜下腔出血、血胸、多发肋骨骨折、鼻骨骨折.认为遇难者系交通事故致颅脑损伤、胸腔脏器损伤死亡.64层螺旋CT扫描结果显示遇难者颅脑、胸部、腹部、骨盆及脊柱多器官、多脏器发生严重的损伤.结论 64层螺旋CT可获得比尸表检验更多、更重要的组织器官和脏器损伤信息,两者联合应用,可为道路交通事故伤情鉴定提供更充分、可靠的依据.Objective To investigate the value of 64-slice multislice computed tomography （MSCT）in full-body postmortem examination after a road traffic accident.Methods The process of road traffic accident involving a pedestrian was obtained from scene monitoring photographic recordings and scene investigation photos.First,the external autopsy was performed by professional forensic pathologist who then reported the autopsy results.Then,64-slice MSCT was employed to perform a full-body scanning,when the CT sectional images were processed with muhiplanar and 3D reconstructions.The CT imaging results were then compared with the autopsy findings to find difference.Results The external autopsy found many soft tissue injuries over the body,subarachnoid hemorrhage,haematothorax,multiple rib fractures and nasal bone fractures and viewed that craniocerebral injury and thoracic injury caused the death after road traffic accident.While 64-slice MSCT revealed severe injuries in many organs including head,chest,abdomen,pelvis and spine.Conclusions Compared with the external autopsy,64-slice MSCT can obtain more important information of tissue and organ injuries.Combined use of 64-slice MSCT and external autopsy can provide sufficient and reliable proofs for identification of road traffic accident injuries.
