摘　　要：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。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.
