Scatterplot showing participant age (in years; horizontal axis) and image quality (an aggregated measure of noise-to-contrast ratio, coefficient of joint variation, inhomogeneity-to-contrast ratio, and root-mean-squared voxel resolution, ranging from 0–1; vertical axis). Dot color indicates whether the participants passed visual quality checks (pass = turquoise; fail = salmon)
