通过综合大流行之前和期间高被引用的研究，调查 COVID-19 大流行是否以及如何改变了医学影像趋势。在这项横断面研究中，我们从基本科学指标 (ESI) 中确定了高被引用的医学影像研究数据库将其分为两个时期：疫情前（2016年1月-2019年12月）和疫情期间（2020年1月-2023年12月）。我们进行了全球研究格局比较分析，并利用 CiteSpace 和 VOSviewer 软件创建知识图谱来分析该领域关键词和参考文献的共现情况。本研究共纳入了 2914 篇高被引研究，结果显示显着的 30.1大流行期间医学影像出版物的增长百分比。国际合作得到加强，欧洲国家和美国主导了研究工作。关键词分析显示，人工智能（AI）在疫情爆发前和疫情期间仍然是医学影像研究的主导热点。参考文献分析显示，人们的注意力转向了与 COVID-19 相关的研究，掩盖了包括癌症成像、心脏成像和神经成像在内的一些重要领域。在过去的四年里，COVID-19 大流行导致了研究成果的变化，国际上高度引用的医学影像研究中的合作和热点。在后新冠时代，当务之急是继续促进国际合作，优先分配资源，重新关注被忽视的研究领域，并制定长期战略计划，为未来公共卫生危机做好准备并减轻其影响。 COVID-19 大流行已经改变了医学影像趋势和优先事项，这对于应对未来公共卫生危机至关重要，但目前尚不清楚。研究结果 COVID-19 大流行导致高引用医学影像研究的增加、国际合作的加强以及研究热点的转变。临床相关性 这项研究全面概述了大流行之前和期间被高度引用的医学影像研究，强调了人工智能在后新冠时代的关键作用，并强调需要重新关注可能被忽视的研究领域。© 2024。作者(s)，经欧洲放射学会独家许可。

To investigate whether and how the COVID-19 pandemic has changed medical imaging trends by synthesizing the highly cited studies before and during the pandemic.In this cross-sectional study, we identified highly cited studies on medical imaging from the essential science indicators (ESI) database, categorizing them into two periods: before the pandemic (January 2016-December 2019) and during the pandemic (January 2020-December 2023). We conducted a global research landscape comparative analysis and utilized CiteSpace and VOSviewer software to create knowledge maps for analyzing the co-occurrences of keywords and references in this field.A total of 2914 highly cited studies were included in this study, which revealed a notable 30.1% increase in medical imaging publications during the pandemic. Enhanced international cooperation has been observed, with European countries and the US leading the research efforts. Keyword analysis revealed that artificial intelligence (AI) has remained a dominant hotspot in medical imaging research before and during the pandemic. References analysis showed a shift in focus towards COVID-19-related studies, overshadowing some important areas including cancer imaging, cardiac imaging, and neuroimaging.Over the past four years, the COVID-19 pandemic has led to changes in the research output, international collaborations, and hotspots within highly cited medical imaging studies. Navigating the post-COVID era, it is imperative to continue fostering international collaboration, prioritize resource allocation to refocus on overlooked research areas, and develop long-term strategic plans to prepare for and mitigate the impact of future public health crises.Question Understanding how the COVID-19 pandemic has changed medical imaging trends and priorities, which is crucial for preparing against future public health crises, remains unclear. Findings The COVID-19 pandemic has led to increases in highly cited medical imaging studies, enhancements in international collaborations, and shifts in research hotspots. Clinical relevance This study provides a comprehensive overview of highly cited studies on medical imaging before and during the pandemic, highlighting the pivotal role of AI in the post-COVID era and emphasizing the need to refocus on potentially neglected research areas.© 2024.
