The aim of this study was to evaluate use of the microblogging social network Twitter by academic radiology departments (ARDs) in the United States.
Twitter was searched to identify all accounts corresponding with United States ARDs. All original tweets from identified accounts over a recent 3-month period (August to October 2014) were archived. Measures of account activity, as well as tweet and link content, were summarized.
Fifteen ARDs (8.2%) had Twitter accounts. Ten (5.5%) had "active" accounts, with ≥1 tweet over the 3-month period. Active accounts averaged 711 ± 925 followers (maximum, 2,885) and 61 ± 93 tweets (maximum, 260) during the period. Among 612 tweets from active accounts, content most commonly related to radiology-related education (138), dissemination of departmental research (102), general departmental or hospital promotional material (62), departmental awards or accomplishments (60), upcoming departmental lectures (59), other hospital-related news (55), medical advice or information for patients (38), local community events or news (29), social media and medicine (27), and new departmental or hospital hires or expansion (19). Eighty percent of tweets (490 of 612) included 315 unique external links. Most frequent categories of link sources were picture-, video-, and music-sharing websites (89); the ARD's website or blog (83); peer-reviewed journal articles (40); the hospital's or university's website (34), the lay press (28), and Facebook (14).
Twitter provides ARDs the opportunity to engage their own staff members, the radiology community, the department's hospital, and patients, through a broad array of content. ARDs frequently used Twitter for promotional and educational purposes. Because only a small fraction of ARDs actively use Twitter, more departments are encouraged to take advantage of this emerging communication tool.
本研究旨在评估美国学术放射科（ARDs）对微博社交网络Twitter的使用情况。
通过搜索Twitter来识别与美国ARDs相对应的所有账户。对最近3个月期间（2014年8月至10月）已识别账户的所有原创推文进行存档。总结账户活动以及推文和链接内容的相关指标。
15个ARDs（8.2%）拥有Twitter账户。其中10个（5.5%）为“活跃”账户，在3个月期间发布了≥1条推文。在此期间，活跃账户平均有711±925名关注者（最多2885名），发布了61±93条推文（最多260条）。在活跃账户发布的612条推文中，内容最常涉及放射学相关教育（138条）、部门研究成果传播（102条）、部门或医院的一般宣传材料（62条）、部门奖项或成就（60条）、即将举行的部门讲座（59条）、其他医院相关新闻（55条）、针对患者的医疗建议或信息（38条）、当地社区活动或新闻（29条）、社交媒体与医学（27条）以及部门或医院新员工招聘或扩张（19条）。80%的推文（612条中的490条）包含315个独特的外部链接。链接来源最常见的类别是图片、视频和音乐分享网站（89个）；ARD的网站或博客（83个）；同行评审期刊文章（40个）；医院或大学的网站（34个）、大众媒体（28个）和Facebook（14个）。
Twitter为ARDs提供了一个机会，使其能够通过广泛的内容与自身工作人员、放射学界、所在医院以及患者进行互动。ARDs经常将Twitter用于宣传和教育目的。由于只有一小部分ARDs积极使用Twitter，因此鼓励更多部门利用这一新兴的交流工具。
