Introduction: The value of a blog as an educational tool is thought to be underestimated by health care professionals. This research aimed to explore the MRI educational utility of blogs, and to determine who was participating in writing those blogs. It was hoped that this research would increase awareness of alternative education formats that would be useful for MRI technologists. Methods: Between March and April of 2017, an online blog search was performed using MRI-related keywords. Strict exclusion criteria were then applied. Two coders independently used lean coding to analyse selected blog posts and organized the codes into themes. Data were tested for intercoder reliability. Results: Researchers analysed 39 posts from 9 blogs and identified the following themes: focus on MRI techniques and technologies, knowledge dissemination, sharing of experience, collaborative learning, authorship, and informal writing. Bloggers, self-identified as practitioners or scholars, communicated about research projects and used an informal writing style. Evidence of intentional teaching of MRI-specific content and sharing of professional and personal experiences was found. Communication between authors and readers from most of the MRI professions was observed, with the exception of MRI technologists. Conclusions: This research found that MRI-related blogs provide a credible and accessible forum for the sharing and discussion of knowledge, experiences, and ideas. Although many MRI professionals author blogs, MRI technologists do not seem to participate in this form of communication. As social media gains in popularity within the medical radiation technologist profession, it is hoped that more MRI technologists will make use of blogging to facilitate learning, collaboration, and communication.
