When Sumer Sethi, MD, started his radiology site in 2004, the word blog was still a relatively recent invention, a shortening of the more formal term weblog. “In different fields, people had started to use weblogs as platforms for communicating with readers without the need for an expensive platform or publishing house,” Sethi (editor-in-chief of the Internet Journal of Radiology) says. “I thought, ‘A blog can be my platform to share my radiology cases and ideas online,’ and that got me started.”

Meanwhile, "radblogging," as it has been nicknamed by Sethi and others, is a growing trend. Samir Shah, a radiologist with Virtual Radiologic (vRad), is a radblogger of a different, but increasingly common, stripe; along with colleagues, he contributes to the nationwide practice’s blog ( "We thought it was a good way for our radiologists to get their voices heard," Shah says. "We can communicate a lot of ideas in a rapid fashion.”

Sethi sees his blog as an interactive, educational resource for his fellow clinicians: “My readers are radiologists, both practicing and in training, in addition to other physicians interested in radiology. My blog has become a learning resource not just for others, but for me as well—sometimes, when I have a doubt, I Google it and land back on my own page,” he says.

Radblogging Versus Academic Writing

Radblogging, as it has been nicknamed by Sethi and others, rarely garners so much as a mention in the academic press—and that, he says, is a reflection of both its origins and its potential. “Web 2.0 is not about big publishing houses or static information websites,” Sethi says. “It’s a dynamic, interactive, and pulsating system wherein ordinary people can convey things and get responses. There’s no software to learn or download, and there’s no requirement for membership to become an editor.”

Shah also notes the differences between radblogging and traditional publishing. “A lot of us at vRad have academic backgrounds, but academics doesn’t always have to be the way to publish ideas,” Shah notes. “It’s antiquated. It’s more fun, and more suits our tastes, to discuss all sorts of ideas in this forum.”

That’s not to suggest that radblogging is a Wild West of information exchange; both Sethi and Shah adhere to certain standards when self-publishing online. Sethi, who often posts images from his own second-opinion practice, ensures that these images are anonymized to comply with HIPAA regulations. He also requires that guest contributors provide references for any clinical information that they provide. At vRad, Shah and his fellow radbloggers “decided to keep our posts a little less controversial,” he says, “and at the end of each post, we ask one thematic question—but that’s it, as far as rules go.”

Getting Started

As Sethi’s comments highlight, launching a personal radblog is easy; building it into a community, however, requires work. “Try to maintain continuity,” Sethi advises. “Initially, you may not develop an audience, but it builds up gradually. Blog about your niche and your passions, and more people will follow you.”

For vRad, the blog “is a relatively new idea,” Shah says. “A lot of people make a lot of assumptions about teleradiology because they don’t know any teleradiologists personally. They go by what they hear." In keeping with Sethi’s advice, Shah found that blogging about new technology—particularly Apple products—was a niche that attracted him. “A lot of people might think, do you really want to be talking so much about Apple? To that I say yes, because that’s what everyone else is talking about.”

He says that a recent post about the iPad 3 garnered particular interest from the blog’s readership. “I mentioned some technical specifications of the iPad 3 and some of the software that’s built into it,” he says. “I think I primed the audience to ask the next logical question, which is whether this will be the future platform for PACS.”

For practices that want to launch a blog, Shah recommends having a champion (at a high level) to guide neophytes in developing social-media presences while maintaining certain standards. “There are negatives with social media, too,” he notes. “Things can often deteriorate into a lot of trolling
