CT在法医病理学中的应用与展望

Application and Prospect of CT in Forensic Pathology

计算机断层扫描(CT)能够对不同密度的人体组织进行成像,在疾病和损伤的检验中具有重要的应用价值,随着CT技术的不断发展和逐步成熟,它可以对组织脏器进行容积再现、多层面重建、最大密度投影、表面遮盖显示等后处理,在肿瘤、血管畸形等疾病的诊断,骨折、关节异位、脏器破裂、出血等损伤的检验,枪弹、爆炸碎片、吸入物等体内异物的检验中具有重要的应用价值。目前已经有不少学者将其应用到相关研究领域当中。本文对近几年国内外应用CT技术进行法医病理学研究的情况进行综述,以便法医病理学研究者了解CT在法医病理学领域中的应用及研究现状,能够为今后的法医病理学科学研究和实践工作提供新的思路。

Computed tomography（CT）,an imaging device using computer two-dimensional reconstruction,can obtain images of body＇s cross-section based on the different X-ray absorption rate of human tissues.CT＇s density resolution is significantly better than that of the X-ray＇s,making it able to conduct the volume and multiplanar reconstructions（VR）,maximum intensity projection（MPR）,shaded surface displays（SSD） and other process.CT has an important value in diagnosis of tumors,vascular malformations and other diseases,fractures,joint ectopia,organ rupture,bleeding injury,gunshot,fragments exploded out,inhalant substances and other foreign materials in the body.CT has been applied in forensic pathology.In this article,we reviewed some papers published in recent years in forensic science journals domestic and abroad to show the present CT applications in forensic pathology,hoping to provide new ideas for forensic pathological research and casework.
