Contrast-enhanced ultrasound (CEUS) technology has been developed for decades, and its application is becoming increasingly more extensive. In this study, bibliometrics was used to characterize the development status of CEUS over the past 20 years and to identify future research hotspots.
We collected data from the Web of Science and analyzed the literature related to CEUS published from 2002 to 2022. We examined 6,382 publications and analyzed the publication year, country of origin, affiliated institutions, authors, journal, categories, keywords, and research frontiers within the relevant literature. Using bibliometric analysis, we aimed to determine the general research direction and current publication trends. This allowed us to identify the most prolific and outstanding authors, institutions, countries, and keywords in CEUS research. For data collection, analysis, and visualization, we employed VOSviewer (Leiden University, Leiden, the Netherlands), Excel (Microsoft Corp., Redmond, WA, USA), CiteSpace, and biblioshiny. These tools helped us gather, analyze, and visualize the data effectively.
The analyzed publications indicated a consistent upward trend in the number of works published between 2002 and 2022. Notably, China and Sun Yat-sen University emerged as the most prolific countries and institutions, respectively. China published 391 articles with 5,817 citations and was the leader in terms of international cooperation. Moreover, pediatrics-related keywords have surged in frequency in recent years.
The amount of research on CEUS has increased rapidly and continues to grow, with China being at the forefront of this research field. The application of CEUS in some pediatric diseases is a recent research hotspot and perhaps warrants close attention.
超声造影（CEUS）技术已发展了数十年，其应用越来越广泛。在本研究中，采用文献计量学方法来描述过去20年CEUS的发展状况，并确定未来的研究热点。
我们从科学网收集数据，分析2002年至2022年发表的与CEUS相关的文献。我们审查了6382篇出版物，并分析了相关文献中的出版年份、原产国、附属机构、作者、期刊、类别、关键词和研究前沿。通过文献计量分析，我们旨在确定总体研究方向和当前的出版趋势。这使我们能够识别CEUS研究中最多产和最杰出的作者、机构、国家和关键词。为了进行数据收集、分析和可视化，我们使用了VOSviewer（荷兰莱顿大学）、Excel（美国华盛顿州雷德蒙德市微软公司）、CiteSpace和biblioshiny。这些工具帮助我们有效地收集、分析和可视化数据。
分析的出版物表明，2002年至2022年期间发表的作品数量呈持续上升趋势。值得注意的是，中国和中山大学分别成为最多产的国家和机构。中国发表了391篇文章，被引用5817次，在国际合作方面处于领先地位。此外，与儿科相关的关键词近年来出现频率激增。
CEUS的研究数量迅速增加且持续增长，中国处于该研究领域的前沿。CEUS在一些儿科疾病中的应用是最近的研究热点，可能值得密切关注。
