Brain ultrasonography has emerged as a key tool in neurocritical care. This study aimed to investigate the global research trends and future research directions in the application of brain ultrasonography for craniocerebral diseases using quantification and visualization approaches. Publications on brain ultrasonography published between 2004 and 2024 retrieved from the Web of Science Core Collection database were screened against predetermined inclusion and exclusion criteria and analyzed. The data were processed using VOSviewer and CiteSpace to identify core countries/regions, institutions, authors, journals, collaborations, and research trends. Over the past 2 decades, 1251 articles focusing on brain ultrasonography as the primary subject were published across 455 journals by 5655 authors from 1619 institutions in 84 countries/regions. Publications exhibited a fluctuating and gradually progressive trend, with the number of publications per year peaking between 2019 and 2021. The USA, the United Kingdom, and Germany emerged as leading countries in this field, demonstrating robust cooperation with other countries/regions. Additionally, the University of Leicester and Panerai RB was the most prolific institution and author, respectively. The clinical applications of brain ultrasonography have progressively broadened from neurocritical care to encompass the general intensive care unit and emergency department. Finally, recent scholarly attention has primarily been directed toward the "deep learning framework" and "hypoxic-ischemic brain injury." Globally, publications focusing on brain ultrasonography displayed a fluctuating and gradually progressive trend over the past 2 decades. Moreover, primary clinical applications and techniques have been constantly expanding. Overall, the findings of our study expanded our understanding of the current status of brain ultrasonography, potentially guiding future development directions in this field.
脑超声检查已成为神经重症监护中的一项关键工具。本研究旨在采用量化和可视化方法，调查脑超声检查在颅脑疾病应用中的全球研究趋势和未来研究方向。从Web of Science核心合集数据库中检索2004年至2024年间发表的关于脑超声检查的文献，根据预先确定的纳入和排除标准进行筛选并分析。使用VOSviewer和CiteSpace处理数据，以确定核心国家/地区、机构、作者、期刊、合作情况和研究趋势。在过去20年中，来自84个国家/地区1619个机构的5655名作者在455种期刊上发表了1251篇以脑超声检查为主要主题的文章。发表情况呈现出波动且逐渐上升的趋势，每年发表的文章数量在2019年至2021年间达到峰值。美国、英国和德国成为该领域的主要国家，与其他国家/地区开展了强有力的合作。此外，莱斯特大学和沛纳海RB分别是发文量最多的机构和作者。脑超声检查的临床应用已从神经重症监护逐渐扩展到涵盖普通重症监护病房和急诊科。最后，近期学术关注主要集中在“深度学习框架”和“缺氧缺血性脑损伤”上。在全球范围内，过去20年中关于脑超声检查的文献呈现出波动且逐渐上升的趋势。此外，主要临床应用和技术一直在不断扩展。总体而言，我们的研究结果扩展了我们对脑超声检查现状的理解，可能为该领域未来的发展方向提供指导。
