Enhancing Brain Age Estimation with a Multimodal 3D CNN Approach Combining Structural MRI and AI-Synthesized Cerebral Blood Volume Measures
NeutralArtificial Intelligence
- A new multimodal BrainAGE framework has been developed, integrating structural MRI and AI-synthesized cerebral blood volume measures to enhance brain age estimation. This approach utilizes two separate 3D VGG-based networks, trained on 2,851 scans from 13 datasets, to improve predictions related to neurobiological aging and disease risk, particularly in conditions like Alzheimer's disease and mild cognitive impairment.
- This advancement is significant as it addresses limitations in current brain age estimation methods, which primarily rely on T1-weighted structural MRI. By incorporating functional vascular information through AICBV maps, the framework aims to provide a more comprehensive understanding of early neurodegeneration, potentially leading to improved diagnostic and therapeutic strategies.
- The integration of multimodal data in predicting Alzheimer's disease reflects a growing trend in neuroimaging research, emphasizing the importance of combining structural and functional assessments. This approach aligns with ongoing efforts to enhance predictive accuracy in cognitive decline models, highlighting the need for innovative methodologies that can capture the complexities of neurodegenerative diseases.
