Figure 6.

Day-to-different-day variability of 154 serial paired global CFR measurements among the analogue 2D GE DST, the 3D United µMI550, and the 3D GE DMI PET-CT. (A) Linear correlation of measurement one and measurement two. (B) Bland–Altman plots differences of serial CFR measurements. (C) Bland–Altman plot of relative percentage differences between serial CFR measurements. (D) Clinical example from Graphical Abstract A with severe, fixed, relative stress defect over 13 years, the CFR improved over the years of intense lifestyle-medical management without invasive procedures, illustrating the importance of reproducibility for personalized CAD management and randomized trials.
