Abstract
Formal and informal lifelong learning allows nuclear medicine professionals to grow and change over time within this dynamic field. Over the past two decades, internet-based websites have provided instantaneous access to informal learning opportunities, including nuclear medicine reference articles, videos and webinars, and case-based learning. More recently, medical educators have explored social media platforms including Instagram, Facebook, and Twitter to provide nuclear medicine education. This article discusses the use of Instagram as a platform for lifelong learning in nuclear medicine. Several nuclear medicine Instagram sites are introduced and user characteristics and participation for a representative site are presented in an effort to learn more about this educational forum, which is increasingly being recognized among academic educators.
