The objective of this study is to conduct a bibliometric analysis of all ultrasound-related publications in the Science Citation Index (SCI).
A search on the databases of the SCI was performed covering the period of 1991-2006. All selected documents stated "ultrasound" as a part of the title, abstract, or keywords in the two fields of "acoustics" and "radiology, nuclear medicine, and medical imaging." Analyzed parameters included authorship, total number of publications in each year, document type, and the authors' keywords. The data were recorded by publication year except the authors' keywords, which were grouped into four periods: 1991-1994, 1995-1998, 1999-2002, and 2003-2006.
A total of 17,775 documents were found, of which 85% were original articles. The yearly production increased from 740 (1991) to 1,208 (2006). The United States dominated with the most publications. The trend towards prenatal research declined in the last 4 years, while Doppler ultrasound research increased during 1999-2006.
Periodic performance of bibliometric analysis of the ultrasound journals may reveal research trends. The most represented topics of ultrasound research are Doppler, prenatal diagnosis, MRI, contrast medium, and vascular studies.
本研究旨在对科学引文索引（SCI）中所有与超声相关的出版物进行文献计量分析。
在SCI数据库中进行检索，涵盖1991年至2006年期间。所有选定文献在“声学”和“放射学、核医学与医学成像”两个领域的标题、摘要或关键词中提及“超声”。分析参数包括作者身份、每年的出版物总数、文献类型以及作者关键词。数据按出版年份记录，但作者关键词分为四个时期：1991 - 1994年、1995 - 1998年、1999 - 2002年和2003 - 2006年。
共找到17775篇文献，其中85%为原创文章。年发表量从1991年的740篇增至2006年的1208篇。美国发表的文献最多。产前研究的趋势在过去4年有所下降，而1999 - 2006年期间多普勒超声研究有所增加。
定期对超声期刊进行文献计量分析可能揭示研究趋势。超声研究中最具代表性的主题是多普勒、产前诊断、磁共振成像、造影剂和血管研究。
