64排螺旋CT三维重建技术在骨盆骨折诊断中的价值及临床应用

目的探讨64排螺旋CT三维重建技术,即多平面重建（MPR）、最大密度投影（MIP）及容积再现（VR）在骨盆骨折诊断中的价值及临床应用。方法使用64排螺旋CT对46例骨盆伤患者扫描,在工作站进行MPR、MIP及VR图像重建,同时与X线平片、二维CT图像进行对比。结果 MPR、MIP及VR重建图像可以清晰地显示骨折的细节,VR重建可以直观立体地显示骨盆骨折手术后的治疗效果。结论三维重建技术是诊断骨盆骨折的有效手段,是复杂性骨盆骨折术前诊断和术后复查的首选检查方法。

The clinical application and value of 64-slice spiral CT in diagnosis of pelvic fracture using three-dimensional technique

Objective To evaluate the application and value of multi-planar reconstruction（MPR）,maximum intensity projection（MIP） and volume rendering（VR） with 64-slice spiral CT in diagnosis of pelvic fracture.Methods 64-slice spiral CT scanning was performed in 46 patients with pelvic trauma.The MPR,MIP and VR images were reconstructed by work station.The results were compared with the findings obtained from X-ray plain film and two-dimensional CT（2DCT）.Results MPR,MIP and VR images could demonstrate the details of pelvic fracture clearly.VR could stereoscopically display the surgical treatment effectiveness.Conclusion The three-dimensional techniques of 64-slice spiral CT are effective method in diagnosis of pelvic fracture,and should be the first choice for diagnosis of complicated pelvic fracture before and after the surgical reduction.
