Table 1 Comparison of myocardial blood flow (MBF) estimates (in ml/g/min) using automated vs. manual AIF measurements

From: Evaluation of an automated method for arterial input function detection for first-pass myocardial perfusion cardiovascular magnetic resonance

(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]*
  1. 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)
