Understanding distribution of published pediatric imaging research in radiology journals is relevant to understanding the state of research in the field.
To understand the current state of published original pediatric imaging research in major clinical radiology journals other than Pediatric Radiology.
We reviewed clinical imaging journals from among the top 20 radiology journals according to the Google Scholar h5-index as of June 2024. Content pages were reviewed for the years 2019-2023 to identify pediatric original research. Study titles were reviewed to subclassify by pediatric subspecialty. The number of citations for each pediatric article and for all articles in the journal was documented, and a citation to article ratio was calculated. The Wilcoxon signed-rank test was used to assess differences in citation to article ratio.
Nine journals and 636 pediatric articles were included. The fraction of pediatric studies in each journal ranged from 0.9% (12/1,310) to 15.3% (244/1,594) (median 2.2% [88/3,983]). Pediatric neuroimaging studies were the most common (46.4% [295/636] of all pediatric studies, 23.2% [91/392] of pediatric studies in journals other than American Journal of Neuroradiology). The citation to article ratio for pediatric articles ranged from 3.3 to 25.2 across journals. Overall, the citation to article ratio for pediatric studies was not significantly different from non-pediatric studies (P=0.12).
Pediatric research makes up a small fraction of original research in major clinical radiology journals, with neuroimaging reflecting the bulk of published work. The average number of citations per pediatric article is similar to that of non-pediatric articles.
了解放射学杂志上已发表的儿科影像研究分布情况，对于理解该领域的研究现状具有重要意义。
了解除《儿科放射学》之外的主要临床放射学杂志上已发表的原创儿科影像研究的现状。
我们根据截至2024年6月谷歌学术的h5指数，对排名前20的放射学杂志中的临床影像杂志进行了回顾。对2019 - 2023年的内容页面进行审查，以确定儿科原创研究。审查研究标题，以便按儿科亚专业进行分类。记录每篇儿科文章以及该杂志所有文章的被引次数，并计算被引文章比率。采用Wilcoxon符号秩检验来评估被引文章比率的差异。
纳入了9种杂志和636篇儿科文章。每种杂志中儿科研究的占比从0.9%（12/1310）到15.3%（244/1594）不等（中位数为2.2% [88/3983]）。儿科神经影像研究最为常见（占所有儿科研究的46.4% [295/636]，在美国神经放射学杂志以外的杂志中，儿科研究占23.2% [91/392]）。各杂志中儿科文章的被引文章比率在3.3至25.2之间。总体而言，儿科研究的被引文章比率与非儿科研究没有显著差异（P = 0.12）。
儿科研究在主要临床放射学杂志的原创研究中占比很小，神经影像研究反映了已发表工作的大部分内容。每篇儿科文章的平均被引次数与非儿科文章相似。
