Comparison of myocardial blood flow (MBF) estimates (in ml/g/min) using automated vs. manual AIF measurements

(ml/g/min)	Rest MBF	Stress MBF
Manual	1.11 [1.06, 1.16]	3.18 [3.01, 3.36]
Auto. 75 % (default)	1.14 [1.09, 1.20]	3.09 [2.96, 3.35]
Auto. 50 %	1.15 [1.09, 1.19]	3.21 [3.08, 3.41]
Auto. 25 %	1.17 [1.11, 1.23]	3.41 [3.22, 3.65]*

All results were calculated using AIFs measured from the dedicated AIF series. Results are expressed as the median and 95 % confidence interval. Automated results significantly different from the manual reference standard are marked with *(p < 0.05)
