AI Tool Predicts Brain Age, Cancer Survival, and Other Disease Signals
Mass General Brigham investigators have developed a robust new AI foundation model that is capable of analyzing brain MRI datasets to perform numerous medical tasks, including identifying brain age, predicting dementia risk, detecting brain tumor mutations, and predicting brain cancer survival. The tool, known as BrainIAC, outperformed other, more task-specific AI models and was especially efficient when limited training data were available. BrainIAC is a foundation model trained and validated on nearly 49,000 diverse brain MRI scans to identify key neurological health indicators without needing extensively labeled datasets. Results are published in Nature Neuroscience.
“BrainIAC has the potential to accelerate biomarker discovery, enhance diagnostic tools, and speed the adoption of AI in clinical practice,” says corresponding author Benjamin Kann, MD, of the Artificial Intelligence in Medicine Program at Mass General Brigham. “Integrating BrainIAC into imaging protocols could help clinicians better personalize and improve patient care.”
Despite recent advances in medical AI approaches, there is a lack of publicly available models that focus on broad, brain MRI analysis. Most conventional frameworks perform specific tasks and require extensive training with large, annotated datasets that can be hard to obtain. Furthermore, brain MRI images from different institutions can vary in appearance and be based on their intended applications (such as in neurology vs oncology care), making it challenging for AI frameworks to learn similar information from them.

“By using concepts from metamaterials, we were able to guide radiofrequency fields more efficiently and demonstrate how advanced physics can directly improve medical imaging. This work shows a pathway toward faster, clearer MRI scans that could benefit patients in many clinical areas.”

COVER STORY
Stretched Too Thin
Burnout is a significant problem in radiology. Experts recommend overhauling workflow to bring medical imaging into the AI age.
FEATURE
The Real Deal on Synthetic Images
Even radiologists and AI programs have difficulty spotting the differences between real and synthetic images, but the threat to health care is relatively low.
