ChatGPT vs. Radiologists

The team analyzed 150 MRI reports of brain tumors written in Japanese before surgery. Both ChatGPT and a group of radiologists, including two neuroradiology experts and three general radiologists, were asked to give different diagnoses and make a final decision.

Subsequently, their accuracy was calculated based on the actual diagnosis of the tumor after its removal. The results stood at 73% for ChatGPT, a 72% average for neuroradiologists, and a 68% average for general radiologists.

How AI Accuracy Varies with Different Radiologist Reports

Additionally, ChatGPT’s final diagnosis accuracy varied depending on whether the clinical report was written by a neuroradiologist or a general radiologist. The accuracy with neuroradiologist reports was 80%, compared to 60% when using general radiologist reports.

“These results suggest that ChatGPT can be useful for preoperative MRI diagnosis of brain tumors,” stated graduate student Mitsuyama. “In the future, we intend to study large language models in other diagnostic imaging fields with the aims of reducing the burden on physicians, improving diagnostic accuracy, and using AI to support educational environments.”
