(STUDY FINDS) – Can a machine do a better job of diagnosing patients after an X-ray or MRI? The latest version of ChatGPT, an artificial intelligence (AI) chatbot, is capable of passing a radiology board-style exam, researchers report. Study authors with the Radiological Society of North America (RSNA) believe this work highlights the potential of large language models while simultaneously revealing the limitations that hamper reliability.
ChatGPT uses a deep learning model to recognize patterns and relationships between words to generate surprisingly human-like responses based on the questions people pose. However, researchers say it’s very important to understand that while ChatGPT may do a great job of impersonating human dialogue, there is no source of truth in its training data, meaning the tool can generate responses that may be factually incorrect.

“The use of large language models like ChatGPT is exploding and only going to increase,” says lead study author Rajesh Bhayana, M.D., FRCPC, an abdominal radiologist and technology lead at University Medical Imaging Toronto, Toronto General Hospital in Toronto, Canada, in a media release. “Our research provides insight into ChatGPT’s performance in a radiology context, highlighting the incredible potential of large language models, along with the current limitations that make it unreliable.”
