摘　　要：目的　了解我国影像学研究中诊断性试验 (diagnosistest)的现状及能否向临床提供可靠的诊断。方法　作者对我国医学影像界影响最大的《中华放射学杂志》进行了人工查阅 ,并根据国际公认标准对所发表的诊断性试验进行了分析。结果　检索 1979～ 1999年《中华放射学杂志》2 1卷共16 2期 ,论著 2 888篇 ,无一期漏检。在所有论著类文章中 ,诊断试验仅占 9% ,其中仅 8 9%与金标准进行独立盲法对比 ,同时计算了敏感性、特异性、准确性等较完整的统计学指标的仅占 2 4%。计算似然比、阳性和阴性预检值的文章数仅分别占 0 5 %、6 %和 5 7%、10 %。结论　我国影像学领域诊断性试验的数量与质量还远远不能满足临床的需要。改进研究方法 。Objective To analyze the status quo of applying diagnosis test in imaging scientific study in China, and to see whether reliable diagnosis can be provided to clinicians for accurate guidance of clinical management. Method We manually looked up diagnosis tests published in 1979～1999 'Chinese Journal of Radiology' that is quite influential in our country. Then we evaluated each of these diagnosis tests according to the International Standards. Results We totally searched 2 888 articles in which only 9% were diagnosis tests. Of these diagnosis tests, only 8.9% applied blind comparison with Gold Standard, 24% calculated sensitivity, specificity and accuracy in the same time. And only 0.5%?6% and 5.7% respectively calculated likelihood ratios, negative predictive value and positive predictive value. Conclusion In China, the quality and quantity of the diagnosis tests applied in the specialty of imaging scientific study is far from meeting the clinical demand. Improving methods of scientific study and carrying on more diagnosis tests of high quality are of important significance to improving the diagnostic level of imaging.
