摘要： 目的探讨多层螺旋CT(MSCT)及其图像后处理功能在骨折法医鉴定中的诊断与应用价值。方法对366例法医鉴定者行薄层扫描并进行表面遮盖成像(SSD),透明化X线模拟投影(see-through)和多平面重建(MPR)处理。对所得图像进行诊断和分型。结果准确诊断并对134例鼻骨、98例眼眶和21例颅骨骨折进行分型。正确显示36例肋骨骨折、4例肩胛骨骨折、24例脊柱骨折和27例四肢骨及关节骨折。利用透明化X线模拟投影等技术鉴别陈旧性骨折18例。结论MSCT及图像后处理在骨折法医鉴定中具有重要实用价值,可为伤害等级鉴定提供有力的法医学依据。

Abstract: Objective To discuss the diagnosis and application of MSCT and post-processing images to fractures in forensic identification. Methods 366 cases were examined by thin slice scanning with MSCT and diagnosed with MPR, see-through and SSD. The final images were analyzed and classified respectively. Results There were 134 cases of nasal fracture, 98 cases of orbital fracture and 21 cases of cranial fracture were confirmed and classified. 36 cases of rib fracture, 4 cases of scapular fracture, 24 cases of spinal fracture and 27cases of limb or joint fracture were displayed clearly in MSCT images. 18 cases of old fracture were distinguished by See-through etc. Conclusion MSCT and post-processing images might be of practical significance and can provide powerful evidences to forensic identification.
