【摘要】 目的：探讨放大像与普通Ｘ线平片对同一部位骨质病变的诊断效果。材料与方法：对２１０例（男１２０例、女９０例）既有Ｘ线平片又有放大像的病例所摄照片进行分析、对比。结果：放大像发现病变的阳性率为７２％；Ｘ线平片发现病变的阳性率为５９％。结论：当临床高度怀疑有骨质病变，常规Ｘ线平片表现为正常或怀疑异常时，应摄放大像以减少漏诊。更多还原

【Abstract】 Purpose: To evaluate the sensitivity of magnification radiography as compared with conventional X ray film. Materials and methods: The results of 210 subjects (120 males, 90 females) with magnification radiograph and conventional X ray film of the same site (bone and joint) performed concurrently were reviewed. Results: The sensitivity of the two methods in detecting diseases was 72% for magnification radiograph and 59% for conventional X ray film. Conclusion: Magnification radiograph should be performed in cases clinically suspected of bone and joint diseases and yet with negative conventional radiograph.更多还原
