DR在疲劳骨折中的应用

目的：探讨DR在疲劳骨折诊断中，与普通X线摄影相比有哪些优势。方法：收集应用DR和普通X线摄影检查、并经临床确诊为疲劳骨折各30例，对2组X线表现进行对比、研究。结果：应用DR检查组，骨折线、骨髓腔内横行致密带（内骨痂）及骨膜增生的显示率分别为86．7％、80．0％、100．0％；应用普通X线检查组，三者的显示率分别为43．0％、33．0％、66．7％。结论：DR和普通X线摄影相比，图像更加清晰，诊断信息明显增加，同时可以较大幅度减少X线辐射荆量，实现图像网络化。

Application experience of DR in fatigue fracture

Objective To discuss the advantages of DR in fatigue fracture diagnosis compared with the plain X-ray photography. Method 30 cases performed DR and 30 cases performed plain X-ray check were collected respectively as two groups, all of which have been diagnosed as fatigue fracture clinically. Research and comparison were made to the two groups. Results In DR group, the percentage of showing fracture line, across medullary cavity of bones compact zone and periosteal proliferation were 86.7%, 80% andl00% respectively, while the plain X-ray group were 43%, 33% and 66.7%. Conclusion Compared with plain X-ray, DR shows better imaging with more diagnostic information, and meanwhile it can greatly reduce the X-ray radiation and computerize the imaging.
