16排螺旋CT三维重建技术在鼻骨骨折诊断中的应用

目的探讨16排螺旋三维重建技术对鼻骨骨折诊断的应用价值。方法对47例鼻外伤病例采用16排螺旋CT行常规横断位非螺旋薄层扫描后,再行多平面重建(MPR)、最大密度投影(MIP)及容积重建(VR),观察鼻骨损伤细节,同时与二维图像进行对比。结果 MPR、MIP、及VR技术可以清晰地显示鼻骨骨折细节,并能明确的鉴别横断位所显示的非骨折性透亮线影。结论 16排螺旋CT结合MPR、MIP及VR等后处理技术在鼻骨骨折中具有重要的诊断价值,能有效的减少过诊、漏诊。

APPLICATION OF 16 SLICE SPIRAL CT THREE-DIMENSIONAL RECONSTRUCTION TECHNIQUE IN DIAGNOSIS OF NASAL BONE FRACTURE

Objective：To investigate the application value of 16 slice spiral 3D reconstruction technology in the diagnosis of nasal bone fracture. Methods： 47 cases of nasal trauma were encountered by 16 slice spiral CT routine axial non helical scan, and then multi-planar reconstruction （MPR）, maximum intensity projection （MIP） and volume rendering （VR）, observing the details of nasal bone injury, and it was compared with the two-dimensional image. Results： MPR, MIP, and VR technology can clearly display the details of nasal bone fracture, and identify the non-fracture radiolucent lines showed by transverse position. Conclusion：16 slice spiral CT combined with MPR, MIP and VR after treatment technology has important diagnostic value in nasal bone fracture, can effectively reduce misdiagnosis, missed diagnosis.
