Figure 8 Results of the Absolute Flow Measurements in Humans

(A) Ratio of thermodilution flow (Q_thermo) before and after percutaneous coronary intervention versus ratio of coronary fractional flow reserve (FFR_cor) before and after percutaneous coronary intervention, and corresponding Bland-Altman diagram of the relative difference. (B) Reproducibility of all measurements. (C) High versus low infusion rate. (D) Distal versus proximal location of sensor.
