MSCT后处理技术对月骨周围脱位的诊断价值

目的：探讨MSCT多平面重组（MPR）和容积再现（VR）技术在月骨周围脱位诊断中的价值。方法：回顾性分析14例月骨周围脱位患者的MPR及VR影像资料。结果：MPR及VR重组图像清晰显示14例月骨周围脱位及伴随19处骨折;MPR显示月骨周围脱位位置明确,骨折线显示清晰,VR显示脱位图像直观、立体感强,脱位的空间位置及骨碎片移位情况比MPR更清晰。结论：MPR、VR可为诊断月骨周围脱位提供重要信息。

Value of multi-slice CT with post-processing technique in the diagnosis of perilunate dislocation

Objective：To investigate the clinical value of MSCT with multiplanar reformation （MPR） and volume rendering （VR） techniques in the diagnosis of perilunate dislocation.Methods：The MPR and VR images in 14 patients with perilunate dislocation were analyzed retrospectively.Results Of 14 patients having perilunate-dislocation,the dislocation as well as the accompanied 19 fractures were displayed clearly on MPR and VR images.The position of perilunate dislocation could be accurately displayed on MPR images as well as the fracture lines could be showed clearly.VR were better than MPR in directly showing the dislocation with definite stereotype and spatiality as well as the displacement of fracture fragments.Conclusion：Important information for the diagnosis of perilunate dislocation could be provided by MSCT with post-processed MPR and VR techniques.
