Relationship between β-amyloid burden and episodic memory in mild cognitive impairment. There was a significant correlation between β-amyloid (Aβ) burden and memory impairment, which was independent of hippocampal volume. Dotted line, threshold between high and low Aβ burden. amMCI, amnestic multidomain mild cognitive impairment; asMCI, amnestic single-domain mild cognitive impairment; naMCI, nonamnestic mild cognitive impairment; SUVR, standard uptake value ratio.
