目的探讨MSCT及后处理技术在眼眶骨折法医鉴定中的应用价值。方法采用MSCT对98例法医鉴定者进行薄层扫描并行多平面重建(MPR)和表面遮盖成像(SSD)处理。比较MSCT与常规CT诊断结果。结果爆裂骨折51例(52.04%),直接骨折32例(32.65%),复合骨折11例(11.22%),未见骨折4(4.09%)例。常规CT漏、误诊32例(32.65%)。98例患者经MSCT检查明确诊断。二者诊断结果存在显著统计学差异(χ2=66.00,P<0.001)。结论MSCT及后处理技术在眼眶骨折法医鉴定中具有较高的实用价值。
Objective To explore the value of MSCT and post-processing techniques in forensic identification of orbital fracture. Methods 98 cases of forensic appraisers were scanned by multi-planar reconstruction (MPR) and surface occlusion imaging (SSD) with MSCT. Compare MSCT with conventional CT diagnosis. Results There were 51 cases of burst fracture (52.04%), 32 cases of direct fracture (32.65%), 11 cases of complex fracture (11.22%) and 4 cases (4.09%) of fracture. Conventional CT drain, misdiagnosed 32 cases (32.65%). 98 patients were diagnosed by MSCT examination. There was a significant difference between the two diagnostic results (χ2 = 66.00, P <0.001). Conclusion MSCT and post-processing techniques have high practical value in the forensic identification of orbital fractures.
