虚拟解剖技术在医疗纠纷尸体检验中的应用

目的探讨CT扫描技术在医疗纠纷死亡原因鉴定中的应用价值。方法在2017年7月至2018年12月间,对12例医疗纠纷案例行全身CT检验,比较CT影像诊断与解剖所见及生前与死后CT诊断的差异性,分析尸体的CT常规检验在病变与损伤的诊断方面的优势与劣势。结果 CT影像诊断与解剖所见比较显示,在密度改变差异大的病变和损伤的诊断方面CT检验存在优势,如肺不张、肺炎、钙化、骨折、出血等;生前与死后CT诊断的比较显示医疗纠纷案件的尸体保存都较为良好,死后CT扫描检验对生前疾病诊断具有意义。结论虚拟解剖技术在医疗纠纷尸体检验中有较高的应用价值,可在尸体解剖前为鉴定人提供有效信息,也可在无法进行解剖的情况下为死亡原因分析提供参考依据。

Application of Virtual Anatomy Technology in Postmortem Examination of Medical Dispute Cases

Objective To discuss the application value of CT scanning technology in cause of death determination of medical dispute cases. Methods From July 2017 to December 2018, postmortem CT imaging data of 12 medical dispute cases were collected. CT imaging diagnosis results and anatomy findings as well as differences between antemortem and postmortem CT diagnosis were compared. The advantages and disadvantages of CT routine tests of the cadavers in terms of the diagnosis of disease and damage were analyzed. Results The comparison between CT imaging diagnosis and anatomical findings showed that CT scans had advantages in the diagnosis of disease and damage with large differences in density changes, such as atelectasis, pneumonia, calcification, fracture and hemorrhage, etc. The comparison of CT diagnosis in antemortem and postmortem examination showed that the cadavers of medical dispute cases were well preserved and that postmortem CT scan was meaningful for the diagnosis of antemortem diseases. Conclusion Virtual anatomy technology has a relatively high application value in postmortem examination of medical dispute cases. It can provide effective information for the appraisers before the autopsy and can also provide a reference for cause of death analysis when the anatomy cannot be performed.
