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.

Accuray announces FDA clearance of iDMS Data Management System

Accuray, a Sunnyvale, California-based radiation oncology company, announced Monday that it has received 510(k) clearance from the FDA for its iDMS Data Management System, a database that shares data between different Accuray delivery systems. The company views this new database as an upgrade to its entire TomoTherapy platform.

MRI offers less invasive peek at potential liver donors

Transplantation is the most effective method of combatting end-stage liver disease. But the success has increased demand and limited supplies for cadaveric organs. In a study, published online July 27 in the American Journal of Roentgenology, researchers examined how MRI can improve evaluation procedures of living liver donors.

AI ‘learns’ to predict schizophrenia from brain MRI

A collaborative effort between IBM and the University of Alberta in Canada has produced artificial intelligence (AI) and machine learning algorithms were able to examine MRI and predict schizophrenia with 74 percent accuracy.

Agfa Healthcare announced Thursday that the XERO Xtend functionalities of its Enterprise Imaging zero-footprint viewer have received FDA 510(k) clearance. These new features provide the company’s XERO Universal Viewer with 3D processing capabilities and “advanced clinical applications.”

How accurate are volumetric software programs when compared to breast MRI?

Radiologists are in need of accurate methods for assessing a patient’s percent breast density (PBD) from a 2D mammogram. Are today’s volumetric breast density software programs up to the challenge?

MRI shows 'residual echo' from Neanderthals in human brain

Researchers from the National Institute of Mental Health have used MRI to suggest the brain’s ability to use tools and locate objects can be connected to Neanderthal-derived gene variants.

Health IT specialists: The unsung heroes of value-based care

Radiology’s shift to value-based care has caused providers to focus on patient experience more than ever before. What makes patients happy? What makes them comfortable? How do you get them more involved in their own care? Asking these questions is the easy part, of course—it’s answering them and then making those answers a reality that can be a significant challenge.

FDA OKs MRI system for use in neonatal ICU

In a June 20 press release, the U.S. Food and Drug Administration (FDA) announced it had cleared the first MRI device designed for neonatal brain and head imaging in intensive care units.

3D imaging provides deeper look into blood clots

Researchers have developed a new method of studying blood clots in 3D through optical microscopy. Such understanding of the internal architecture of clots can help cardiologists identify and diagnose clots that may put patients at risk for stroke or heart attack.
