FIG. 6.

Bland-Altman plots showing the comparison of mean stress perfusion estimates between each of the four quantitative analysis methods used in this study. The same axis value ranges were used in each case to facilitate comparisons. The most notable observation from this plot is that the largest bias between perfusion estimates between models occurs with the Fermi function model at stress versus the other three models.
