Quantitative assessment of myocardial blood flow in coronary artery disease by cardiovascular magnetic resonance: comparison of Fermi and distributed parameter modeling against invasive methods

Table 5 Results from ROC analysis for all Fermi versus DP modeling comparisons

Statistics	Fermi vs DP modeling (Per vessel)	Fermi vs DP modeling (Per patient)
P values from comparisons of ROC curves between models
MBF	0.01*	0.0065*
MPR	0.02*	0.0089*
MPR₂	0.21	0.0064*
Difference in AUC of ROC curves between models
MBF	-0.08 (-0.15,-0.02)	-0.11 (-0.19,-0.03)
MPR	-0.10 (-0.18,-0.02)	-0.09 (-0.16,-0.02)
MPR₂	-0.05 (-0.13, 0.03)	-0.07 (-0.12,-0.02)

Statistically significant differences are indicated with *. Comparisons in per vessel and per patient analysis are presented. Parentheses show 95 % confidence intervals. DP distributed parameter modeling, MBF myocardial blood flow, MPR myocardial perfusion reserve, MPR ₂ myocardial perfusion reserve of the two lowest scoring segments, AUC area under the curve
