Comparison of diastolic and systolic T1 mapping images in patients with AF. Example images output by T1 mapping in patients with AF. a-b: a AF patient with heart rate ranged from 54 to 74 bpm during scan. a presented the motion corrected IR images acquired at system default diastolic trigger delay, the second image (as shown in the green box) was mistriggered at systolic phase; b presented the motion corrected IR images acquired at systolic phase, the images are in consistent contour. c-d: a AF patient with heart rate ranged from 72 to 112 bpm. c presented the motion corrected IR images acquired at system default diastolic phase, the 7th and 8th images (marked with green box) were mistriggered at systolic phase; d presented the motion corrected IR images acquired at systolic phase, no mistriggered images was found
