The value of 16-Slice Spiral CT Scanning and 3D Reconstruction in diagnosis of the occult fracture pelvis

目的探讨16排螺旋CT扫描及三维重建技术在骨盆隐匿性骨折诊断中的应用价值。方法回顾性分析67例骨盆外伤患者的16排螺旋CT扫描及三维重建后的影像学资料,即多平面重建(MPR)及容积再现(VR),同时与普通X线摄片(DR)图像进行对比。结果 X线检查检出骨折89处,CT检查检出骨折143处,其中包括X线检查为阴性的隐匿性骨折和X线检查为阳性的其他部位隐匿性骨折。结论 16排螺旋CT扫描及三维重建技术是诊断骨盆隐匿性骨折的有效手段,提高骨折的检出率,对骨折的分类、诊断及治疗具有重要意义。

Objective To investigate the value of 16-slice spiral CT scanning and 3D reconstruction in diagnosis of the occult fracture pelvis application. Methods Retrospectively analyzed 67 cases patients with pelvic fracture of 16- slice spiral CT scanning and 3D reconstruction image data, Consist of multi-planar reconstruction （MPR） and volume rendering technique （VR）, the results were compared with x-ray plain films （DR）. Results 89 pelvis fractures in 67 patients were displayed clearly by x-ray plain, and 143 pelvis fractures by CT, consist of occult fracture that x-ray plain failed to demonstrate injuries whereas the fractures of pelvis were clearly visualized on transverse plane CT im- ages and 3D reconstruction. Conclusion The 16-slice spiral CT scanning and 3D reconstruction are effective method in diagnosis of pelvic occult fracture, should improve the detection rate of fracture. It is important of classification, diagnosis and treatment.
