In keeping with the unprecedented nature of 2020, the annual Radiology Society of North America meeting was, for the first time ever, held in a virtual format. It marked only the third time in the society’s history of over 100 years that it did not converge in person. The previous two times? 1943 and 1945, due to transportation and gasoline supply issues during and immediately following World War II.

Fortunately, the virtual meeting had much to offer, including an abundance of industry unveilings, partnerships and promising research findings. Here are some of the stories from RSNA that were most read in our online news:

Addressing bias in AI
During a session looking at bias in artificial intelligence, Dr. Ziad Obermeyer, an associate professor of health policy and management at the UC Berkeley School of Public Health, spoke about the “pain gap” between Black and white patients when evaluating them as candidates for a knee replacement.

He noted that moving away from the Kellgren and Lawrence (KLG) system for classification of osteoarthritis, and finding data sets that link images to a patient’s experience of pain, could more than double the number of Black patients deemed eligible for knee replacement surgery.

“There’s a big difference between predicting what the radiologist says about the knee and predicting what the patient experience is,” Obermeyer said.

GE enters 3D surgical imaging market
GE Healthcare entered the $200 million 3D surgical imaging market with the unveiling of OEC 3D, a C-arm designed to provide surgeons with 2D and 3D views of a patient's anatomy during operations.

The solution is designed to integrate into existing surgical workflows and is equipped with a 3D image reconstruction engine that is meant to provide high-resolution volume reconstructed CT-like images. These scans are expected to allow surgeons to visualize exactly where they are operating in 3D so they can be precise in their actions.

OEC 3D was among 27 new products and features released by GE at RSNA, with many aligned with its focus on COVID-19 care.

Resolving global disparities with tech
More than half of the world has little or no access to radiology services, according to the World Health Organization. Neuroradiologist Dr. Bhavya Rehani, president and co-founder of Health4TheWorld, attributes this to a lack of education and training, and says modern technology can help resolve the problem.
