a
T1 (in milliseconds, mean ± standard deviation in a region of interest covering most of the septal wall) for single-shot inversion recovery-FLASH at 43 ms resolution (19 spokes) and 3 s duration. #Frames refers to the number of images retained after deletion of systolic frames.
b
Mean ± standard deviation across subjects.
