AI Now Can Predict Brain Age From an MRI Scan
This could help doctors spot Alzheimer's years before symptoms start.
Deep Dive
A new AI framework sharpens brain-age estimation by combining structural MRI with synthetic cerebral blood volume maps, giving a fuller picture of ageing than either alone. In tests on thousands of scans, the combined
Key Points
- AI can now estimate brain age using MRI scans and AI-synthesized blood flow maps.
- The tool is more accurate than current methods and may detect dementia 3-4 years sooner.
- It works without expensive dyes, making it faster and cheaper for hospitals.
Why It Matters
Could help catch Alzheimer's earlier, when treatment might still work, and save lives and money.
