a) Calculated T1 values from phantom images acquired with different simulated R-R interval of 60-120 beats per minute. T1 measurements calculated from MOLLI shows linearly dependent on the duration of R-R, however SAPPHIRE T1 measurements were relatively constant. b) T1 maps from two healthy subjects acquired without gadolinium contrast showing higher homogeneity of the T1 measurements in SAPPHIRE.
