多排螺旋CT多平面重建在四肢复杂小关节外伤中的诊断价值

目的：评价多排螺旋CT（MDCT）的多平面重建（MPR）技术对诊断四肢复杂小关节外伤的价值。方法：收集50例四肢复杂小关节外伤患者，行螺旋CT薄层扫描，并在工作站上进行MPR重建。结果：50例外伤患者MPR图像全部清晰显示其骨折情况，无1例漏诊，而仅CT轴位图像有4例骨折未显示或显示不清晰。结论：MDCT的MPR技术能充分利用CT图像信息，在不同的方位及角度显示骨折的特征，有很高的临床应用价值。

Multidetector computed tomography multi-planar reconstruction in the diagnosis of complicated membra minor articulus trauma

Objective：To evaluate the value of the Multidetector computed tomography （MDCT）multi-planar re-construction（MPR）in complicated membra minor articulus trauma. Methods：50 cases with complicated membra mi-nor articulus trauma received the MDCT thin-layer scanning , All data were entered into the computer workstation to get MPR images.Results：The MPR images clearly showed the fracture in all 50 patients,and no one misdiagnosed.4 cases without MPR technology were misdiagnosed. Conclusion：MDCT MPR can make full usage of CT image informa-tion and display the characters of fracture clearly in different directions and angles, which have important value in the clinical application.
