目的：探讨多层螺旋CT（multislice CT，MSCT）三维及多平面重建在肋软骨损伤中的临床应用价值。方法：19例肋软骨损伤患者均采用MSCT 5 mm扫描，0.625 mm重建后作三维及多平面重建。扫描所得数据通过网络传送至计算机工作站处理，采用AW4.3平台上三维重建软件进行三维重建。结果：本组19例共32处肋软骨骨折，其中2例3处位于肋软骨与胸骨交界区，13例25处位于肋软骨中间区域，4例4处位于肋软骨与肋骨交界区，并合并肋骨骨折15例。螺旋CT三维重建图像能清晰显示肋软骨骨折部位、骨折数量。结论：螺旋CT三维及多平面重建能明确显示肋软骨骨折、移位情况，容积再现、最大密度投影及多平面重建3种重建模式的相互结合对诊断肋软骨骨折及指导临床及时准确地制订治疗方案有明显优势。

To explore the clinical application value of 3-dimensional and multiplane reconstruction with MSCT in diagnosing costal cartilage trauma. Totally 19 cases with costal cartilage trauma underwent MSCT 5 mm scanning and 0.625 mm reconstruction, and then went through three-dimensional and multiplane reconstruction. The ac-quired data were transmitted to the computer workstation through the network, and then three-reconstruction was per-formed with the software on AW4.3 platform. There were all 32 costal cartilage fractures in the 19 patients in-volving 15 cases with rib fracture, which included 2 cases and 3 fractures at the chondrosternal junction, 13 cases and 25 fractures in the middle of the costal cartilage, 4 cases and 4 fractures at the junction between costal cartilage and rib. Three-dimensional reconstruction with spiral CT could display clearly the location and number of costal cartilage frac-tures. Three-dimensional and multiplane reconstruction shows clearly the fracture and displacement of the costal cartilage, and the combination of MRP, MIR and VR may contribute to the diagnosis and clinical planning of the costal cartilage fracture.
