Description

● The Adolescent Brain and Cognitive Development (ABCD) Study has publicly shared a large (~12,000 subjects), high-quality dataset collected on 21 different MRI scanners.

● Scans show variance across scanners that is similar in magnitude to age/sex effects.

● Empirical Bayes methods (ComBat) do a pretty good job of eliminating scanner variance, though it is not complete.
