    "excerpt": "AI foundation model advances comprehensive brain MRI analysis.\n\nMass General Brigham investigators have developed a robust new artificial intelligence (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. Results are published in Nature Neuroscience.\n\nDespite 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 based on their intended applications (such as in neurology versus oncology care), making it challenging for AI frameworks to learn similar information from them.\n\nTo address these limitations, the research team designed a brain imaging adaptive core, or BrainIAC. The tool uses a method called self-supervised learning to identify inherent features from unlabeled datasets, which can then be adapted to a range of applications. After pretraining the...",
