Global research trends and focus of Lung Ultrasound: A Bibliometric Analysis
The purpose of this study was to summarize the knowledge structure of pulmonary ultrasound through bibliometric analysis, and to discuss potential research trends and priorities. Publications related to pulmonary ultrasound were selected from the Science Core Collection website before March 2, 2023. Use VOSviewer(version 1.6.18), CiteSpace(version 6.1.3), and Rstudio's free online platforms (http://bibliometric.com) for co-write, co-cite, and co occurrence analysis of countries, institutions, authors, references, and keywords in the field. And the visual analysis is carried out. A total of 1057 papers were included. Since 2013, research papers based on lung ultrasound have increased. In terms of published articles, Italy has contributed the most in this area. The institutions and authors we think have been most productive are the University of Milan and Luna Gargani. The top three journals with the most published articles are the 《JOURNAL OF ULTRASOUND IN MEDICINE》, 《DIAGNOSTICS》 and 《PEDIATRIC PULMONOLOGY》. According to the results of literature and keyword analysis, "covid-19", "SARS-CoV-2", "PoCUS", "deep learning" and "lung ultrasound score" have been identified as the main research directions in the future. Pulmonary ultrasound is in the stage of vigorous development and has a broad prospect. The development of pulmonary ultrasound will be the focus of future research.Abstract
