European Radiology: ChatGPT detects brain tumors with doctor's precision

Scientists from Osaka Metropolitan University Graduate School of Medicine found that ChatGPT can diagnose brain tumors from MRI images with the accuracy demonstrated by board-certified neuroradiologists. The study results were published in the journal European Radiology.

ChatGPT (Generative Pre-trained Transformer) is a chatbot using generative artificial intelligence created by OpenAI. According to researchers, neural networks are increasingly being used in various scientific fields, including radiology. Large language models such as ChatGPT can even aid in diagnosis or offer second opinions.

To evaluate the medical potential of ChatGPT, scientists provided the program with data from 150 pre-operative brain MRI reports. Based on daily clinical notes in Japanese, ChatGPT, along with two board-certified neuroradiologists and three general radiologists, assessed the presence of brain tumors.

The diagnostic accuracy of ChatGPT was 73%, compared with 72% and 68% for neuroradiologists and general radiologists, respectively. ChatGPT performance results varied depending on the clinical report author. When using written materials from a neuroradiologist, accuracy reached 80%, and from a general radiologist – 60%.

In the future, the scientists plan to explore the use of large language models in other areas of diagnostic imaging, which will reduce the workload of doctors and improve diagnostic accuracy.
