This study aimed to evaluate the correlation of longitudinal changes of amplitude low-frequency fluctuation (ALFF) and regional homogeneity (ReHo) values based on Harvard-Oxford atlas (HOA) and Barratt Impulsivity Scale 11 (BIS-11) in subjects with methamphetamine abstinence. The results suggested that there were significant positively correlations between right middle frontal gyrus (8) and BIS total scores, BIS attention scores as well as BIS non-planning score.
