Brain-age estimates can be reliable with ultra-low-field scans
Four leading approaches had average absolute errors of 6.7–8.21 years against actual ages in 23 adults scanned with ultra-low-field magnetic resonance imaging.Four leading approaches had average absolute errors of 6.7–8.21 years against actual ages in 23 adults scanned with ultra-low-field magnetic resonance imaging.

What changedBrain-age estimates varied across pipelines, but top ultra-low-field combinations showed test-retest reliability of ICC = 0.97 -0.99
The catchOnly 23 adults were scanned, so chance findings and unstable rankings cannot be excluded
