Background Podcasts have become an increasingly popular method of communicating information in medicine, including in radiology. However, the effect of podcasts on the reach of journal articles remains unclear. Purpose To evaluate the influence of podcasts on the performance metrics, including downloads, citations, and Altmetric Attention Score (AAS), of articles. Materials and Methods This was a retrospective study. All articles published in the print version of from January 2021 to December 2022 were reviewed; editorials and case reports were excluded. Articles featured on podcasts were included in the podcast group. Articles published within the same journal issue and category were the nonpodcast group. Downloads, Google Scholar citations, Dimensions citations, and AAS metrics were recorded. The Mann-Whitney test was used to compare medians and evaluate differences between older and more recently published articles. Results The podcast group, composed of 88 articles, exhibited significantly higher median values for downloads (PG, 4521.0; nonpodcast group, 2123.0; < .001), Google Scholar citations (podcast group, 14.5; nonpodcast group, 10.0; = .01), Dimensions citations (podcast group, 12.0; nonpodcast group, 9.0; = .01), and AAS (podcast group, 43.0; nonpodcast group, 10.0; < .001) compared with the nonpodcast group of 378 articles. Within both groups, articles published in the earlier nonpodcast group (January to June 2021) had higher downloads (podcast group, = .08; nonpodcast group, < .001), Google Scholar citations (podcast group and nonpodcast group, < .001), and Dimension citations (podcast group and nonpodcast group, < .001) than articles from the later period (July to December 2022). AAS markedly increased in recent podcast articles ( = .03), but AAS for nonpodcast articles significantly decreased over time ( = .01). Conclusion articles featured on the podcast had greater median metrics, including downloads, Google Scholar citations, Dimensions citations, and AAS, compared with nonpodcast articles, suggesting that podcasts can be an effective method of disseminating and amplifying research within the field of radiology. © RSNA, 2024 See also the editorial by Chu and Nicola in this issue.
背景 播客已成为在医学领域（包括放射学领域）传播信息的一种越来越流行的方法。然而，播客对期刊文章传播范围的影响尚不清楚。 目的 评估播客对文章表现指标（包括下载量、引用量和 Altmetric 关注度得分 [AAS]）的影响。 材料与方法 这是一项回顾性研究。对 2021 年 1 月至 2022 年 12 月印刷版 上发表的所有文章进行了回顾性分析；排除社论和病例报告。出现在 播客上的文章被归入播客组。在同一期刊期号和类别中发表的文章归入非播客组。记录下载量、Google Scholar 引用量、Dimensions 引用量和 AAS 指标。采用 Mann-Whitney 检验比较中位数并评估新旧文章之间的差异。 结果 由 88 篇文章组成的播客组的下载量（PG，4521.0；非播客组，2123.0； ＜.001）、Google Scholar 引用量（播客组，14.5；非播客组，10.0； =.01）、Dimensions 引用量（播客组，12.0；非播客组，9.0； =.01）和 AAS（播客组，43.0；非播客组，10.0； ＜.001）中位数均显著高于 378 篇非播客组文章。在这两组中，早期非播客组（2021 年 1 月至 6 月）发表的文章下载量（播客组， =.08；非播客组， ＜.001）、Google Scholar 引用量（播客组和非播客组， ＜.001）和 Dimensions 引用量（播客组和非播客组， ＜.001）均高于后期文章（2022 年 7 月至 12 月）。近期播客文章的 AAS 明显增加（ =.03），而非播客文章的 AAS 随时间推移显著下降（ =.01）。 结论 与非播客文章相比，出现在 播客上的 文章的中位数指标更高，包括下载量、Google Scholar 引用量、Dimensions 引用量和 AAS，表明播客可以成为放射学领域传播和放大研究的有效方法。 RSNA，2024 本期还刊登了 Chu 和 Nicola 的社论。
