摘要: 目的探讨多层螺旋CT(MSCT)及图像后处理在鼻骨骨折法医学鉴定中的应用价值。方法采用MSCT对134例被鉴定人进行薄层扫描并行多平面重建(MPR)和表面遮盖成像(SSD)。比较MSCT与常规X线诊断结果。结果线型骨折55(41.04%)例,粉碎型骨折46例(34.33%),凹陷型骨折27例(20.15%),未见骨折6例(4.48%)。X线平片及CR片漏、误诊48例(35.82%)。MSCT正确诊断133例(99.25%)。两者诊断结果存在显著差异(χ2=45.0816,P<0.001)。结论MSCT及后处理图像应作为鼻骨骨折法医鉴定的主要依据。

Abstract: Objective To evaluate the application of MSCT and post- processing images to fractures of nasalbone in forensic identification. Methods 134 cases were examined by thin slice scanning with MSCT and all ofthe data were sent to workstation for MPR and SSD. The result of MSCT was compared with that of X- ray. Re-sults There are 55 (41.04%) cases of linear fracture, 46 (34.33%) cases of comminuted fracture, 27 (20.15%)cases of depressed fracture and 6 (4.48%) cases of no fracture in this sample. With X- ray or CR, 48 (35.82%)cases were misdiagnosed or underdiagnosed. 133 (99.25%) cases were confirmed by MSCT. Significance differ-ence was found between X- ray and MSCT (χ2= 45.0816,P<0.001). Conclusion MSCT and post- processing im-ages might be the chief evidence for nasal fractures in forensic identification.
