摘要
目的:探讨螺旋CT四维容积重建技术VRT在术前、术后髋臼及骨盆骨折中的诊断价值。材料和方法:使用SiemensPlus4螺旋CT机对8例髋臼及骨盆骨折患者进行扫描,在Siemens工作站利用阈值、不透明度、明亮度的选定完成术前、术后骨盆容积重建,多方位切割观察骨盆解剖结构,并进行术前、术后容积重建图像比较。结果:VRT图像清晰的显示了术前髋臼损伤的立体形态,术后髋臼及骨盆金属内固定物的形态、位置,骨折块复位的效果及骨折愈合期的情况。结论:螺旋CT容积重建技术,是髋臼及骨盆骨折诊断的有效手段,VRT对于术前手术计划的制定及术后手术效果的判断有很高的价值。
Objective:To evaluate the diagnostic value of VRT application to acetabulum fractures.Materials and Methods:Eight cases of acetabulum trauma were examined with Siemens plus 4 spiral CT.The data were reconstructed in workstation with VRT by using different threshold,opacity,brightness,and observing the acetabulum structure from all directions.Then the findings of preoperative were compared with that of postoperative.Result:The reconstructed images of VRT displayed the preoperative structure of acetabulum fractures clearly,VRT images could show the shape and location of the internal fixation from four-dimensional reconstructed technique,and the effect of reposition after operation and the healing state of acetabulum fractures can also be shown.Conclusion:VRT of spiral CT is an effective method in diagnosing acetabulum and pelvis trauma,VRT possesses higher value in making surgical planning and evaluating the effect of surgery.
