CT pulmonary angiography (CTPA) is the investigation of choice for diagnosing pulmonary embolism (PE). Due to the speed and ease of performing the CTPA scans, more clinicians are becoming overly reliant on them, even for patients without strong suspicion of PE. We conducted a bibliometric analysis on the PubMed database from 1990 to 2022 to investigate the literature on the diagnostic yield of CTPA in the diagnosis of PE. A total of 166 articles were published in 98 journals. The number of publications has steadily increased since 2010 and peaked in 2020. Authors from 24 countries contributed to these publications, with the overwhelming majority emanating from United States of America, totaling 66 articles. The authors' contributions were relatively well spread out, with the top four authors publishing the highest number of articles at six each. When we investigated the collaboration between the authors, we found limited multinational and multi-institutional collaborations on this topic. Therefore, more multinational and multi-institutional collaborations will be valuable in future studies. In conclusion, this bibliometric analysis summarizes the literature on diagnostic yield of CTPA in the diagnosis of PE and sheds light on the future pathway that researchers and institutions can focus on.
计算机断层扫描肺动脉造影（CTPA）是诊断肺栓塞（PE）的首选检查方法。由于进行CTPA扫描速度快且操作简便，越来越多的临床医生对其过度依赖，甚至用于对PE怀疑程度不高的患者。我们对1990年至2022年的PubMed数据库进行了文献计量分析，以研究CTPA在PE诊断中的诊断效能相关文献。共有98种期刊发表了166篇文章。自2010年以来，发表数量稳步增加，并在2020年达到峰值。来自24个国家的作者参与了这些出版物，其中绝大多数来自美国，共计66篇文章。作者的贡献分布相对均匀，前四位作者发表文章数量最多，各为6篇。当我们研究作者之间的合作情况时，发现关于该主题的跨国和多机构合作有限。因此，更多的跨国和多机构合作在未来研究中将很有价值。总之，这项文献计量分析总结了CTPA在PE诊断中的诊断效能相关文献，并为研究人员和机构未来可关注的方向提供了启示。
