多层螺旋CT重建技术对未骨化肋软骨骨折的诊断价值

The Value of Multi-slice Helical CT in Diagnosis of Non-calcifed Costal Cartilage Fracture

目的:探讨多层螺旋CT扫描检查对未骨化肋软骨骨折的诊断价值。方法:对12例临床怀疑未骨化肋软骨骨折患者(其中肋骨骨折7例)进行螺旋CT容积扫描,将所有原始数据进行薄层重建后导入Vitrea工作站进行(MPR、MIP、SSD、VR)方法重建,并比较各种重建图像对未骨化肋软骨显示的能力。结果:12例受检者经螺旋CT扫描重建处理后发现未骨化肋软骨骨折3例。重建以MIP、VR技术显示效果为佳,其他技术相互补充。结论:螺旋CT重建图像能很好地显示未骨化肋软骨,是诊断其骨折的一种无创伤性最佳影像学技术。

Objective： To discuss the value of multi-slice Helical CT in diagnosis of non-calcified costal cartilage fractrue. Methods： CT volume scan was performed in 12 cases of non-calcified costal cartilage fractrue,in which there is 7 cases of rib fractrue.All original data was processed to form thin layer reconstruction, and then the reconstruted images were transmitted to Vitrea work-station to perform the image reconstrution by （ MPR, MIP, SSD, VR） methods. The ability of different image techniques in displaying non-calcified costal cartilage was compared. Results： The 3 cases were found non-calcified costal cartilage in 12 cases of multi-slice Helical CT reconstructong image. The MIP ,VR image reconstruction was better than others. Conclusion： Multi-slice Helical CT image reconstructong could display non-calcified costal cartilage perfectly, was the best imaging technique in diagnosis of non-calcified costal cartilage fractrue without trauma.
