We investigated the degree of Japan's contribution to the nuclear medical research in the last decade. Articles published in 1991-2000 in highly reputed nuclear medical journals were accessed through the MEDLINE database. The number of articles having affiliation with a Japanese institution was counted along with publication year. In addition, shares of top-ranking countries were determined along with their trends over time. Of the total number of articles (7,788), Japan's share of articles in selected nuclear medical journals was 11.4% (889 articles) and ranked 2nd in the world after the USA (2,645 articles). The recent increase in the share was statistically significant for Japan (p = 0.02, test for trend). Japan's share in nuclear medical research output is much higher than that in other biomedical fields.
我们调查了日本在过去十年对核医学研究的贡献程度。通过MEDLINE数据库检索了1991年至2000年发表在高声誉核医学期刊上的文章。统计了与日本机构有关联的文章数量以及发表年份。此外，还确定了排名靠前国家的份额及其随时间的趋势。在文章总数（7788篇）中，日本在选定核医学期刊上的文章份额为11.4%（889篇），仅次于美国（2645篇），位居世界第二。日本份额的近期增长具有统计学意义（p = 0.02，趋势检验）。日本在核医学研究产出中的份额远高于其他生物医学领域。
