简介:W.K.Rontgen伦琴报告发现一种新的放射线,物理医学会在1895年12月2813提出并命名为X线。1910年开始用于临床,对肺结核的发现和早期诊断贡献巨大。1936年间接摄影开始应用,对没有症状的表面健康人群进行间接摄影,可发现肺内有可疑阴影者,作为进一步检查的筛选方法,对肺结核早期发现有重要价值,从而为肺结核防治对策向前发展起到推动作用。X线计算机体层摄影(CT),其密度分辨率高、横断面影像的三维投影显示对全面观察胸部病变是普通X线摄影的重要补充,它使放射学的胶片时代进入了计算机影像时代,这是伦琴发现X线后在放射学上一项最有意义的重大发明.

简介:摘要目的比较观察磁共振成像和X线平片在检查类风湿关节炎腕关节病变中的作用。方法选取25例类风湿关节炎患者,其中男5例,女20例,年龄20-75岁,平均46岁,在一星期内进行腕关节X线检查和MR检查。MR成像仪的为0.3T场强,处理含自旋回波T1加权成像,梯度回波T2*加权成像。结果25例临床诊断为类风湿关节炎的患者的50个腕关节中,X线发现14个腕关节有骨侵蚀的表现,MR发现45个腕关节有骨侵蚀的表现。MR检查一共发现156个腕骨的骨侵蚀病灶,而X线平片只发现18个腕骨的骨侵蚀病灶。检查中发现月骨是最容易受累的骨头。在检查类风湿关节炎骨质侵蚀的病变上,两种检查方法之间的分析,统计学差异非常显著(p<0.001)。MR的成像还可以清楚的显示滑膜炎性及水肿改变,增强MR可鉴别关节积液与血管翳。结论检查类风湿关节炎早期的腕关节病变,如骨质侵蚀等,MR比X线检查更优越,倘若X线检查不能发现临床怀疑早期类风湿关节炎,可行MR检查,有助于早期诊断。
