American College of Radiology, Nvidia team up to deploy AI in radiology

The American College of Radiology and tech firm Nvidia are deploying free artificial intelligence software for radiologists to help spur AI adoption.

The platform, called the "Nvidia Clara AI toolkit," was piloted at The Ohio State University in Columbus and the Boston-based Massachusetts General Hospital & Brigham and Women's Hospital Center for Clinical Data Science.   

"Nvidia builds platforms that democratize the use of AI and we purpose-built the Clara AI toolkit to give every radiologist the opportunity to develop AI tools that are customized to their patients and their clinical practice," Kimberly Powell, vice president of healthcare at Nvidia, said in a press release. "Our successful pilot with the ACR is the first of many that will make AI more accessible to the entire field of radiology."

What makes the platform unique is that institutions can collaborate on building and validating AI algorithms, but patient data is kept local.

"This software will offer radiologists, without computer programming experience, the ability to build and improve AI algorithms without the need to share their data," Keith Dreyer, DO, PhD, chief data science officer at Partners HealthCare and associate professor of radiology at Harvard Medical School, both in Boston, said in a press release. "Algorithms typically work best within the sites where they were trained, but those limited training sets are not always representative of the population at large. Training AI models on data from diverse sites helps ensure resiliency while reducing algorithm bias, resulting in improved inference across broader populations."

Nvidia and the American College of Radiology plan to make the platform available to ACR members and other radiologists after ACR's annual meeting May 18-22.
