Technology Management


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.

By one measure of quality, mammography providers have increased their performance from a D grade in 2002 to a B grade this year.

An update issued today from the U.S. Food and Drug Administration on the Mammography Quality Standards Act and Program (MQSA) reveals that 86.9% of all facilities tested in February were free of violations, a vast improvement since 2002, when just 64.2% of facilities achieved that distinction.

Technology Acquisition: Implementing the New Normal

Reimbursement cuts, market consolidation, and health-care reform have sparked significant changes in the imaging-technology strategies being implemented across the radiology landscape. Practices, imaging centers, and hospital radiology departments alike not only are altering the manner in which they formulate decisions on imaging-equipment acquisition, but also are adopting different approaches to demonstrating the need for new technology, to acquiring capital for equipment purchases, and to maintaining the assets that they already have.

Showdown in Missouri: Decision Support Versus RBMs

Two years ago, a friend of Missouri state Rep Caleb Jones (R) sustained a shoulder injury while playing with his child. While a physician suggested that an MRI exam might be in order, the man’s health-insurance provider would not cover the cost of the study and instructed him to seek care from a sports-medicine practice. Forced to jump through multiple hoops to address his injury, the man endured prolonged pain and frustration before learning that he had not just bruised his shoulder; he had sustained a fracture—with which he had been walking around for two weeks.
