Podcasts have surged in popularity as a way to entertain and educate, including within medicine. Although podcast popularity has increased in recent years, there is little work on the effect of podcasts on profiled article impact. The American Journal of Roentgenology (AJR) has a popular podcast profiling recent AJR articles. Our goal was to assess the effect of AJR podcasts on the impact of AJR articles.

Materials and Methods:
Ethics approval was not required, as all data was publicly accessible. All 1008 articles published in the print version of AJR from January 2020 to December 2021 were reviewed. Of these, 634 were excluded (90 best practices, clinical perspectives, opinions, reviews, society-endorsed statements, technical innovations, and video articles, 192 editorial comments, 121 featured articles, 102 commentaries, 80 letters, 29 editorials, 19 corrections, and one article for which metrics could not be found, due to website error), due to having zero articles featured in the podcast. Inclusion as a Continuing Medical Education (CME) credit article or as a Journal Club (JC) article was noted. Articles presented on AJR podcasts were included in the podcast group. Published articles that were never on the AJR podcast were used as controls. Google Scholar citations, Dimensions citations, Altmetric attention scores (AAS), and downloads were gathered. Mann-Whitney U-tests were used to compare the medians, as the two groups had similar data distributions. T-tests could not be performed due to the data being nonparametric.

A total of 374 articles were analyzed, with 106 in the podcast group (P) and 268 in the control group (C). There were a total of 337 Original Research articles (P=93, C=244), 24 Short Report articles (P=9, C=15), 13 Systematic Reviews/Meta-Analyses (P=4, C=9), 108 CME articles (P=39, C=69), and 24 JC articles (P=12, C=12). The mean number of Google Scholar citations (P=11.1 &#177; 12.4, C=9.2 &#177; 12.3), Dimensions citations (P=9.9 &#177; 9.8, C=7.6 &#177; 10.3), AAS (P=30 &#177; 49.5, C=21.4 &#177; 83.1), and downloads (P=2,638 &#177; 2,765, C=1,644 &#177; 2,005) were higher in the podcast group. The podcast group had a higher median number of Google Scholar citations (P=7, C=6, p=0.01468), Dimensions citations (P=7, C=5, p=0.00044), AAS (P=11, C=6, p<0.0001), and downloads (P=2,082.5, C=1,084, p<0.00001). When excluding JC and CME articles, 253 articles remained (P=60, C=193). The podcast group again had a higher median number of Google Scholar citations (P=7, C=6, p=0.19706), Dimensions citations (P=7, C=5, p=0.02202), AAS (P=9.5, C=5, p=0.00932), and downloads (P=2,044.5, C=1,073, p=0.00034).

Articles featured on the podcast had a greater impact across all categories evaluated. Podcasts are an effective and low-carbon footprint method of disseminating and amplifying the knowledge contained in AJR journal articles. In addition to educating and informing on the topic of the highlighted article, the AJR podcast should also be lauded as a way to boost distribution and impact of the article itself.
