To evaluate the methods used in studies comparing magnetic resonance imaging (MRI) and computed tomography (CT) of the brain, we reviewed English language articles published between 1981 and early 1986. Of 83 studies comparing the accuracy of MRI and CT in 10 or more patients, few met methodologic standards for evaluations of the efficacy of new diagnostic tests. Limitations were found in how study populations were assembled, in test performance and interpretation, and in analysis of study findings. Greater attention to design and execution of comparison studies could overcome these limitations and help demonstrate MRI's true diagnostic value.
为评估在比较脑部磁共振成像（MRI）和计算机断层扫描（CT）的研究中所使用的方法，我们回顾了1981年至1986年初发表的英文文章。在83项对10名或更多患者比较MRI和CT准确性的研究中，几乎没有研究符合评估新诊断测试疗效的方法学标准。在研究人群的招募方式、测试执行与解读以及研究结果分析方面均发现了局限性。更加注重比较研究的设计与执行能够克服这些局限性，并有助于证明MRI的真正诊断价值。
