【摘要】 目的探讨64层螺旋CT(VCT)三维重组技术,即多平面重组(MPR)、最大密度投影(MIP)及容积再现(VR)在骨盆骨折诊断中的应用价值。资料与方法使用VCT对48例骨盆损伤患者进行扫描,在GE工作站进行MPR、MIP及VR图像重组进而观察损伤细节,同时与二维CT图像进行对比。结果MPR、MIP及VR重组图像可以清晰地显示骨盆骨折的细节。同时VR重组可以直观立体地显示骨盆骨折手术后的治疗效果。结论VCT三维重组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。更多还原

【Abstract】 Objective To evaluae multi-planar reconstruction(MPR),maximum intensity projection(MIP) and volume rendering technique(VR) in diagnosis of pelvic fracture.Materials and Methods 64 spiral CT scanning(GE 64 VCT) was performed in 48 patients with pelvic trauma.The MPR,MIP and VR images were reconstructed by GE work station.The results were compared with the findings obtained from two-dimensional CT(2DCT).Results MPR,MIP and VR images could demonstrate the details of pelvic fracture clearly.VR could stereoscopicly display the surgical treatment effectiveness.Conclusion The three-dimensional technique of 64 spiral CT are effective method in diagnosis of pelvic fracture,and should be the first choice of complicated pelvic fracture before and after the surgical reduction.更多还原
