RT Journal Article SR Electronic T1 Publicly Available Metrics Underestimate AJNR Twitter Impact and Follower Engagement JF American Journal of Neuroradiology JO Am. J. Neuroradiol.

McCarty YR 2019 UL http://www.ajnr.org/content/40/12/1994.abstract AB SUMMARY: Social media use by professional organizations has increased as a platform to disseminate information, affording an alternative avenue to engage membership and the public. The American Journal of Neuroradiology (AJNR) posts cases and articles, hosts Tweet chats, advertises podcasts, and more on its Twitter account (@TheAJNR). The objective of this study was to determine whether user engagement is underestimated on the basis of publicly available metrics and to assess the engagement rate. This study demonstrated that engagement extends beyond visible metrics, suggesting an AJNR “silent” following beyond what is readily apparent. Median engagement rates from the @TheAJNR account from 2017 to 2019 appear stable since last reported in 2016 and are comparable with those reported in other professional medical journals.ERengagement rate
