Fig. 7From: Quantitative myocardial first-pass cardiovascular magnetic resonance perfusion imaging using hyperpolarized [1-13C] pyruvate(left) Exemplary dynamic perfusion image series acquired in vivo. Myocardial bolus peak occurs between 4 and 6Â s after start of acquisition. Arrows indicate the left anterior descending artery (LAD) (green), left circumflex (LCx) (blue) and right coronary artery (RCA) (yellow). (right) Myocardial bolus peak image summed over two frames. Enhanced signal in the lateral inferior segment is caused by signal leakage from the LCx and signal pile-up stemming from geometric distortions in the EPI image due to local off-resonancesBack to article page
