Knowledge domain and dynamic patterns in multimodal molecular imaging from 2012 to 2021: A visual bibliometric analysis

Multimodal molecular imaging technologies have been widely used to optimize medical research and clinical practice. Bibliometric analysis was performed to identify global research trends, hot spots, and scientific frontiers of multimodal molecular imaging technology from 2012 to 2021. The articles and reviews related to multimodal molecular imaging were retrieved from the Web of Science Core Collection. A bibliometric study was performed using CiteSpace and VOSviewer. A total of 4169 articles and reviews from 2012 to 2021 were analyzed. An increasing trend in the number of articles on multimodal molecular imaging technology was observed. These publications mainly come from 417 institutions in 92 countries, led by the USA and China. K. Bailey Freund published the most papers amongst the publications, while R.F. Spaide had the most co-citations. A dual map overlay of the literature shows that most publications were specialized in physics/materials/chemistry, and molecular/biology/immunology. Synergistic therapy in cancer, advanced nanotechnology, and multimodal imaging in ophthalmology are new trends and developing areas of interest. A global bibliometric and visualization analysis was used to comprehensively review the published research related to multimodal molecular imaging. This study may help in understanding the dynamic patterns of multimodal molecular imaging technology research and point out the developing areas of this field.     

我国磁外科研究中文文献计量学分析

目的:了解国内磁外科研究中文文献发表现状,探讨国内磁外科研究的热点和发展趋势。方法:检索中国知网(CNKI)系列数据库、万方数据知识服务平台及维普期刊资源整合系统自建库至2019年9月30日发表的磁外科研究文献,应用Excel软件建立数据库,整理统计文献相关信息,从年度分布、期刊分布、地域分布、作者分布、机构分布、基金支持、研究类型、研究内容等方面对纳入的209篇文献进行统计分析。结果:磁外科研究文献自2010年以后呈现出明显增长趋势,文献主要分布于国内116种期刊,磁外科相关文献的116位通信作者分布在20个省(市)的69家研究机构,获省部级及以上基金支持的文献占文献总量的47.37%,临床研究类文献占文献总量的41.63%,研究内容为磁导航技术方面的文献占文献总量的61.27%。结论:国内磁外科研究中文文献数量呈明显的上升趋势和集中态势,但研究领域不平衡,发文期刊分散且基金支持不足,磁外科研究进一步发展尚有很大空间。     

A bibliometric analysis of neuroimaging biomarkers in Parkinson disease based on Web of Science

Background:This study aimed to analyze and summarize the research hotspots and trends in neuroimaging biomarkers (NMBM) in Parkinson disease (PD) based on the Web of Science core collection database and provide new references for future studies.Methods:Literature regarding NMBM in PD from 1998 to 2022 was analyzed using the Web of Science core collection database. We utilized CiteSpace software (6.1R2) for bibliometric analyses of countries/institutions/authors, keywords, keyword bursts, references, and their clusters.Results:A total of 339 studies were identified with a continually increasing annual trend. The most productive country and collaboration was the United States. The top research hotspot is PD cognitive disorder. NMBM and artificial intelligence medical imaging have been applied in the clinical diagnosis, differential diagnosis, treatment, and prognosis of PD. The trends in this field include research on T1 weighted structure magnetic resonance imaging in accordance with voxel-based morphometry, PD cognitive disorder, and neuroimaging features of Lewy body dementia and Alzheimer disease.Conclusion:The development of NMBM in PD will be effectively promoted by drawing on international research hotspots and cutting-edge technologies, emphasizing international collaboration and institutional cooperation at the national level, and strengthening interdisciplinary research.     

2001/2010年中国眼病流行病学调查及防盲治盲工作文献计量学分析

目的:从文献计量学的角度分析2001/2010年间国内眼病流行病学调查及防盲治盲工作的研究状况。方法:利用中国科学引文数据库为统计源,检索2001/2010年国内眼病流行病学调查及防盲治盲工作的研究文献,利用文献计量学方法进行统计分析。结果:在中国科学引文数据库中共收集关于眼病流行病学调查及防盲治盲工作相关文献179篇,其年度间变化呈直线上升趋势,《中华眼科杂志》、《国际眼科杂志》是刊载此类文献数量较多的期刊,赵家良教授是报道相关文献最多的专家,其2002年发表的《北京市顺义县50岁及以上人群中青光眼患病率和正常眼眼压的调查》为单篇被引频次最高的文献,所有研究中盲和低视力研究最多,眼底病中糖尿病视网膜病变的流行病学研究也占有较大比例。结论:眼病流行病学调查及防盲治盲工作是眼科科研工作者研究的重点。     

中医药治疗乙肝研究文献计量分析

目的：寻找国内中医药治疗乙肝方面的研究重点和趋势,为其临床诊疗提供参考。方法：利用中国期刊网（CNKI）数据库,通过主题词与自由词结合方式,检索2007—2012年国内中医药治疗乙肝的文献,进行文献计量学分析。结果：6年中,国内关于中医药治疗乙肝的研究文献数量呈增长趋势。结论：中药治疗乙肝、中医辨证治疗乙肝的研究是研究热点,中医特色疗法及中医治疗乙肝的疗效评价标准的研究为新兴研究方向,但研究方法需要规范以提高研究质量。
