方法:向WebofScienceCoreCollection查询了有关双能量和多能量CT以及胸部应用的相关出版物,而没有限制出版日期或语言。Bibliometrix软件包,VOSviewer,和CiteSpace用于数据分析。使用的文献计量技术是共同作者分析,趋势主题,专题地图分析,主题演变分析,源的生产随着时间的推移,相应的作者国家,和作者\'关键字的树图。
结果:这项研究共检查了1992年的出版物和来自313个不同来源的7200名作者。第一份可用文件于1982年11月发布,被引用次数最多的文章被引用了1200次。西门子股份公司在德国成为最杰出的作者隶属关系,共发表221篇文章。最具代表性的科学期刊是“欧洲放射学”(181篇文章,h-index=46),其次是“欧洲放射学杂志”(148篇文章,h-index=34)。大部分论文来自德国,美国,或者中国。关键词和主题分析均显示了双能量和多能量CT的历史及其在胸部应用热点的演变。
结论:我们的研究说明了双能量和多能量CT的最新进展及其在胸部的应用日益突出,尤其是肺实质疾病和冠状动脉疾病。光子计数CT和人工智能将是未来不断发展的新兴热点技术。
■这项研究旨在为胸部疾病的能量成像提供有价值的见解,验证了多能量CT与光子计数CT的临床应用,有效提高了临床利用率。
结论:文献计量学分析是理解双能量和多能量CT当前和未来状态的基础。研究趋势和主要主题包括冠状动脉疾病,肺栓塞,和辐射剂量。所有分析都表明人们对将基于能量的成像技术用于胸部应用越来越感兴趣。
OBJECTIVE: To conduct a bibliometric analysis of the prospects and obstacles associated with dual- and multi-energy CT in thoracic disease, emphasizing its current standing, advantages, and areas requiring attention.
METHODS: The Web of Science Core Collection was queried for relevant publications in dual- and multi-energy CT and thoracic applications without a limit on publication date or language. The Bibliometrix packages, VOSviewer, and CiteSpace were used for data analysis. Bibliometric techniques utilized were co-authorship analyses, trend topics, thematic map analyses, thematic evolution analyses, source\'s production over time, corresponding author\'s countries, and a treemap of authors\' keywords.
RESULTS: A total of 1992 publications and 7200 authors from 313 different sources were examined in this study. The first available document was published in November 1982, and the most cited article was cited 1200 times. Siemens AG in Germany emerged as the most prominent author affiliation, with a total of 221 published articles. The most represented scientific journals were the \"European Radiology\" (181 articles, h-index = 46), followed by the \"European Journal of Radiology\" (148 articles, h-index = 34). Most of the papers were from Germany, the USA, or
China. Both the keyword and topic analyses showed the history of dual- and multi-energy CT and the evolution of its application hotspots in the chest.
CONCLUSIONS: Our study illustrates the latest advances in dual- and multi-energy CT and its increasingly prominent applications in the chest, especially in lung parenchymal diseases and coronary artery diseases. Photon-counting CT and artificial intelligence will be the emerging hot technologies that continue to develop in the future.
UNASSIGNED: This study aims to provide valuable insights into energy-based imaging in chest disease, validating the clinical application of multi-energy CT together with photon-counting CT and effectively increasing utilization in clinical practice.
CONCLUSIONS: Bibliometric analysis is fundamental to understanding the current and future state of dual- and multi-energy CT. Research trends and leading topics included coronary artery disease, pulmonary embolism, and radiation dose. All analyses indicate a growing interest in the use of energy-based imaging techniques for thoracic applications.
