The aim of the study was to compare postmortem computed tomographic (CT) imaging findings from a case of hanging with the autopsy findings. The CT showed a good match with autopsy findings especially for bone, soft tissue, and spinal injuries. The CT images of the injuries of the neck obtained by CT scan clearly showed the ligature mark, the hemorrhagic suffusion in the soft tissue (thickening of derma) and in the muscles (sternocleidomastoid) of the neck. Furthermore, CT 3-dimensional reconstruction showed brain edema, fracture of the left posterior horn of the hyoid bone, and a grade 1 retrolisthesis of C5 on C6. This last finding was not detected by autopsy because of the anterior approach that is frequently used in necropsy technique. Nevertheless, the CT virtual autopsy did not show vascular findings (like Amussat mark) because a barium mixture was not injected in the body.
该研究的目的是比较一例缢死病例的尸体计算机断层扫描（CT）成像结果与尸检结果。CT显示与尸检结果高度匹配，尤其是在骨骼、软组织和脊柱损伤方面。通过CT扫描获得的颈部损伤的CT图像清晰地显示了勒痕、颈部软组织（皮肤增厚）和肌肉（胸锁乳突肌）内的出血性渗出。此外，CT三维重建显示脑水肿、舌骨左后角骨折以及C5椎体相对于C6椎体1级椎体后移。由于尸检技术中常用的前入路方式，最后这一发现未被尸检检测到。然而，尸体CT虚拟解剖未显示血管方面的发现（如阿穆萨特氏斑），因为未向体内注入钡剂混合物。
