目的：探讨16层螺旋CT及后处理技术在肋软骨骨折诊断中的应用价值。方法对39例共52处肋软骨骨折采用胸部16层螺旋CT及后处理技术检查，并对其后处理成像资料进行对比分析。结果后处理成像发现39例52处肋软骨骨折，平扫仅发现17例22处肋软骨骨折。 CT平扫和后处理成像表现特征为未钙化或钙化肋软骨中断伴明显错位；肋软骨内见低密度线条状影，无明显断端分离错位；肋弓明显变形；肋软骨间融合处分离。结论螺旋CT后处理成像对肋软骨骨折诊断有重要价值。“,”Objective To investigate the 16-slice spiral CT and post-processing technology in the costal cartilage fracture diagnosis value. Methods 39 cases of 52 costal fractures chest 16-slice spiral CT examination and post-processing techniques, and subsequently processed imaging data were analyzed. Results 39 cases of post-treatment imaging found 52 costal fractures, only 17 cases of unenhanced found 22 costal fractures. CT scan and post-treatment imaging performance characteristics for non-calcified or calcified cartilage disruption with significant dislocation;cartilage were seen in low-density lines like shadow, no obvious stump isolated dislocation;Legong significant deformation;costal interbody fusion at separation. Conclusion Spiral CT postprocessing imaging cartilage fracture diagnosis has important value.
