多排螺旋CT曲面重建技术在肋骨微细骨折诊断中的价值

摘要

Objective To study the value of Curved Planar Reconstruction(CPR)in the diagnosis of tiny fracture of ribs. Methods 20 patients of no obvious costal fractures after thoracic trauma with MSCT by volume rendering(VR)and multi planar reconstruction(MPR)were analyzed retrospectively to find if there were tiny fractures with CPR. Results 7 ribs in 6 cases were found tiny fractures with CPR. 3 fractures in 2 cases were occurred in left ribs,while 4 in right. 3 fractures located in posterior ribs,2 in corpus costae,and 2 in caput costae. 5 fractures were incomplete ones,while 2 were complete ones. Conclusion MSCT with MPR can show tiny costal fractures well,which has significant clinical value for detection of occult tiny costal fractures.%目的：评价曲面重建技术（CPR）在肋骨微细骨折诊断中的应用价值。方法回顾性分析20例胸部外伤后经螺旋CT扫描并VR、MPR重建显示无明显肋骨骨折，进一步用CPR技术对受损区域肋骨进行重建，观察有否肋骨微细骨折。结果经CPR技术重建显示6例（7根）肋骨骨折：发生在左侧2例（3根），发生在右侧4例（4根）；不完全性肋骨骨折5根，完全性肋骨骨折2根；3根肋骨骨折线位于后肋，2根位于腋侧，2根位于前肋与肋软骨交界处。结论螺旋CT曲面重建技术能很好的显示肋骨微细骨折，对提高肋骨隐性微细骨折的检出率有重要临床意义。
