CT多平面重组在眼眶骨折法医鉴定中的价值

Value of CT Multiplanar Reformation of Orbital Fracture in Forensic Identification

    摘要
  • 摘要: 目的:探讨CT多平面重组(MPR)技术在眼眶骨折法医鉴定中的价值。方法:对87例需要法医鉴定的眼眶外伤患者,行多层螺旋CT容积扫描后,用多平面重组技术重建出标准的轴位、冠状位、斜矢状位(与视神经长轴平行)图像及病情需要的任意角度的平行范围重组(MPR)图像,并对其观察分析。结果:87例眼眶外伤患者中,CT平扫显示眼眶骨折68例,可疑骨折14例,误诊5例。MPR图像多方位结合,明确显示或明确诊断85例,可疑骨折2例,误诊0例。轴位、冠状位、斜矢状位及任意角度的重组图像对眼眶外伤的诊断各有优势。结论:眼眶骨折CT单一方位图像均不利于法医鉴定,多方位结合的重组技术可为法医鉴定提供可靠的诊断依据。

     

    Abstract: Objective:To discuss the value of CT multiplanar reformation of orbital fracture in forensic identification.Methods:87 cases of suspected orbital fracture in forensic identification underwent volume scan of CT.The data were processed using multiplane reformation(MPR) and free angle parallel ranges reconstruction(PRR),and the CT findings were observed and analyzed.Results:In the 87 cases,conventional CT orbital scans show 68 cases of orbital fracture,14 cases of suspected fractures,and 5 cases were misdiagnosed.MPR diagnosed 85 cases of orbital fracture,2 cases of suspected fractures,and no misdiagnosis.Axial,coronal,oblique sagittal and reconstructed images at any angle of the diagnosis of orbital trauma have their own advantages.Conclusion:The single direction of orbital fracture CT images are not conducive to forensic identification,multi-faceted combination can provide reliable forensic diagnosis.
