摘　　要：目的探讨MSCT轴位5mm扫描联合容积再现（VR）、曲面重组（CPIK）在肋骨、肋软骨不完全性骨折中的应用价值。方法1周内临床有明确胸部外伤史患者106例，应用MSCT容积轴位5mm扫描，并对疼痛区的肋骨、肋软骨行VR、CPR后处理，由2名高年资放射科医师，对常规MSCT5mm轴位图像（对照组）与常规MSCT5mm轴位图像联合VR、CPR图像（观察组）进行分组诊断，排除完全性骨折．比较两组双侧不完全性骨折的根数、处数。结果106例患者中-，排除完全性骨折后，对照组发现125根（126处）肋骨、肋软骨不完全性骨折，观察组发现204根（217处）肋骨、肋软骨不完全性骨折，两组比较差异有统计学意义（P〈0．01）。结论MSCT轴位5mm扫描结合VR、CPR能显著提高肋骨、肋软骨不完全性骨折的检出率，是有效而相对快捷的诊断方法，具有重要的临床应用价值。Objective To investigate the application value of axial MSCT scan （ thickness ： 5mm ） combined with volume rendering （ VR ） and curved planar reformation （ CPR ） in the incomplete rib or costicartilage fracture. Methods 106 cases with definite chest trauma history were collected in a week, and axial MSCT 5mm scan was performed. VR and CPR post-processing was utilized in the pain area of rib or costicartilage. Two senior radiologists made diagnosis via the conventional 5mm axial scan images （ control group ） and the images progressed by VR and CPR （ observation group ） respectively. In addition, excluding complete fracture, the number of bilateral incomplete rib or costicartilage fracture and the fracture number in the two groups were compared. Results In the control group, exclusion of complete fracture, 125 rib or costicartilage broken were diagnosed, with 126 fractures, while in the observation group, 204 rib or costicartilage broken were found, with 217 fractures. There was statistical difference between the two groups （ the control group was 1.18 ± 1.08, the observation group we 1.92 ± 1.18, P〈0.01 ） . Conclusion Axial MSCT （ thickness： 5ram ） scan combined with VR, CPR can significantly improve the detection rate of rib or costicartilage incomplete fracture. It has important clinical value as an effective diagnostic method.
