CT图像三维重建在复杂颈椎骨折的诊断和治疗中的应用价值

Application of three-dimensional computed tomogramphy reconstruction in complex cervical spine fracture

目的直观立体地显示复杂颈椎骨折的图像,探讨螺旋CT医学图像三维重建在复杂颈椎骨折诊断中的价值及其对手术的指导意义。方法对113例颈椎骨折采用螺旋CT进行薄层扫描和三维重建进行诊断。CT扫描全部采用S iem ens SOMATOM Sensation 16型多排高速螺旋CT机,1.0mm层厚。扫描所得断层资料,通过网络传送至计算机工作站处理。采用W indow.NT 3.51平合上Insight三维重建软件进行三维重建。结果三维CT图像能够围绕X轴和Z轴任意旋转、切割,以从不同角度观察,能够清晰显示复杂的颈椎骨折和狭窄椎管的解剖形态特点。结论三维CT重建在颈椎骨折方面具有较大的临床应用价值,有助于提高颈椎骨折手术的安全性和精确性,并对患者预后的估计提供帮助。

Objective To present the complex cerivcal spine fracture spqtially,and evaluate the value of three-dimensional computed tomogramphy in the diagnosis of complex cervical spine fracture.Methods Three-dimensional（3D） CT imaging reconstruction was performed using Helical CT in 113 case of cervical spine fractures.The EBISC150XP fast CT was used with section thickeness of 1.0mm.The CT data was transferred to a computer workstation through the net ,and was reconstructed using the “Insight”software on the Windows NT 3.51.Results The 3D CT images could rotate around X and Z axes,and be cut freely and viewed from different perspectives.The anatomy feature of the complex cervical spine fracture and the stenosis of vertebral canal could be presented completely on the 3D images.Couclusion 3D CT is effective in the diagnosis of cervical spine fracture,providing better surgical planning and management.
