| 摘 要： | 目的 评价螺旋CT扫描三维重建成像与X线摄片对比对鼻骨骨折法医学鉴定的价值。方法 使用SOMATOM BALANCE 1s螺旋CT机，对32例复杂鼻部外伤者2mm／2mm扫描，常规进行最大密度投影法(MIP)、多平面重建(MPR)、表面覆盖法(SSD)、容积成像(VR)方式。全貌显示受伤鼻骨骨折影像，并与常规鼻骨摄片比较。结果 螺旋CT三维成像纠正3例X线照片的假阳性和6例诊断骨折类型不准确。结论 螺旋CT三维重建对诊断复杂鼻骨骨折块数目、移位，以及骨折类型优于X线摄片。

| Abstract: | Objective To investigate the advantages of three-dimensional (3-D) reconstruction of nasal fractures with spiral computed tomography (CT) in comparison with roentgenography in medico-legal expertise. Methods CT scanning was performed in 32 cases with complex nasal fractures by Somatom Balance on 2mm/2mm scan. The images were reconstructed with maximum intensity projection (MIP), multi-plannar reconstruction (MPR), shaded surface display (SSD), and volume rendering (VR) mode and compared with roentgenographic images. Result Nasal fractures evaluated by roentgenography were detected to be false-positive in 3 cases and misdiagnosed fracture type in 6 cases as re-evaluated by 3-D reconstruction. Conclusion 3-D reconstruction images are of advantages over roentgenographic images in evaluation of broken bone fragments, displacement, fracture type for clinical diagnosis and medicolegal expertise. |
