As the influence of social media platforms such as Twitter and Facebook grows, healthcare specialists have started adopting specific hashtags on those platforms to reach the largest number of users possible. In interventional radiology, for instance, the preferred hashtag is #IRad. Researchers tracked the evolution of that hashtag on Twitter, publishing their results in the Journal of Vascular and Interventional Radiology.

During a 2016 simulation exercise, researchers evaluated the ability of 32 different deep learning algorithms to detect lymph node metastases in patients with breast cancer. Each algorithm’s performance was then compared to that of a panel of 11 pathologists with time constraint (WTC). Overall, the team found that seven of the algorithms outperformed the panel of pathologists, publishing an in-depth analysis in JAMA.

At RSNA 2017 in Chicago, artificial intelligence (AI) and deep learning technologies were everywhere. Attendees rushed to learn as much as possible about AI, countless educational sessions touched on the topic and exhibitors made sure to mention it in their booths as much as possible. I wouldn’t quite say AI took over the show like some have suggested, but it did make quite an impression on everyone walking through the doors of McCormick Place.

The buzz around social media in radiology has skyrocketed in recent years, with more and more departments, private practices and specialists starting to use using the various platforms to their advantage. Of course, it’s about more than just using sites such as Facebook, Twitter and Instagram; to get the most out of these resources, one must also learn the differences between them.

Interest in artificial intelligence (AI) and machine learning at RSNA 2017 seems like it’s unprecedented—but the increased attention is quantifiable. More than 100 sessions delve into the topic at this year’s show in Chicago. Two years ago, less than 10 touched on such concepts.

Reactor shutdown may lead to Mo-99 shortage

Changes to the worldwide supply chain of molybdenum-99 could lead to drastic shortages of a nuclear medicine tracer over the next 18 months, according to a U.S. National Academy of Sciences report. The National Research Universal reactor in Ontario will shut down at the end of October, and while global supply will be “adequate," the reports judges a 50 percent chance of a substantial shortage until other suppliers complete upgrades.

Affordable anthropomorphic phantoms: Pipe dream or a reality?

A team of researchers in Berlin saw that high costs and a complex manufacturing process were limiting the use of anthropomorphic phantoms of patients in radiology. There must be more affordable and efficient way, they thought.
