We studied the increase in the number of articles in the radiologic literature in the years 1970, 1978, and 1985 using the Medlars program which provides reproducibility, a recognized bibliographic pool, and a wide coverage of the medical literature. A dramatic increase in the number of articles was found; the increase has both positive and negative implications for the profession. A similar analysis of monographs using the Catline file and the same subject headings also showed a significant increase in the volume of material relating to certain radiologic subspecialties. The problems arising from the attempt to identify and extract relevant information from this overwhelming mass of radiological data should be addressed.
我们使用医学文献分析和检索系统（MEDLARS）程序，研究了1970年、1978年和1985年放射学文献中文章数量的增长情况。该程序具有可重复性、公认的书目库以及对医学文献的广泛覆盖。结果发现文章数量急剧增加；这一增长对该专业既有积极影响，也有消极影响。使用医学累积索引（Catline）文件和相同主题词对专著进行的类似分析也表明，与某些放射学亚专业相关的材料数量显著增加。应解决从这大量的放射学数据中识别和提取相关信息时出现的问题。
