DaT View striatal SBRs consistently showed significantly lower values in the aspiration group and negative associations with aspiration in logistic regression models, whereas DaTQUANT exhibited limited significance in intergroup differences and associations. ROC analysis showed DaT View striatal SBR of the better side (SBR<em>better</em>) as the optimal predictor (sensitivity 0.62, specificity 0.93 at cutoff: 2.03).
