摘要 目的探讨数字X线(DR)放大摄影在类风湿性关节炎诊断中的优势。方法对212例住院确诊并且治疗的类风湿性关节炎患者,全部采用DR摄影对其双手和双腕进行投照,把所得影像采用DR后处理技术,尤其是DR放大技术和DR窗宽窗位调节技术对图像进行处理,观察类风湿性关节炎在双手和双腕中软组织、关节间隙和骨组织方面的改变。结果212例中12例仅有软组织肿胀;31例在软组织肿胀的同时可见骨质疏松;65例软组织肿胀合并关节面裸区的1~6个小的骨侵蚀;104例关节面下方见多个小囊状骨破坏区,其中21例合并关节脱位和畸形。结论DR放大摄影在类风湿性关节炎诊断中具有重要作用,是临床正确诊断和早期治疗的首选检查方法。
