Receiver-operating characteristic analysis (ROC) between AL-CA patients with preserved LV systolic function and normal controls. By using the cut-off values of upslope (Green), TTM (Blue) and MaxSI (Red), the first-pass perfusion MR could discriminate the myocardial microvascularity of AL-CA patients with preserved LV systolic function from that of normal controls in the basal (a), mid-ventricular (b) and apex (c) segments
