The relationship between global quantitative first pass perfusion (qFPP) and coronary sinus flow at rest and stress in Iraqi males (open circles) and Swedish born males as controls (open squares). (A) Global qFPP plotted against coronary sinus flow with the dashed lined representing the line of identity and solid line representing linear regression (r = 0.95, y = 0.89x + 0.20). (B) Agreement between qFPP and sinus coronary flow, bias 0.02 ± 0.5 ml/min/g. Dashed lines represent ± 2SD and solid line represent bias.
