Fig. 1From: Association of pulmonary transit time by cardiac magnetic resonance with heart failure hospitalization in a large prospective cohort with diverse cardiac conditionsA Representative first pass perfusion images showing the main pulmonary artery (PA), and left atrium (LA) in standard sagittal views. B Example of time intensity curves obtained from main pulmonary artery (orange) and from left atrium (green) where pulmonary transit time (PTT) is calculated as the time elapsed between the two peaksBack to article page
