Comparison between free breathing and breath-hold methods in MOLLI sequences. (A) The correlation between T1 relaxation time obtained by MOLLI sequence with free breathing and breath-hold methods (Pearson correlation coefficient = 0.993, p < 0.001). (B) Bland–Altman Curve between free breathing and breath-hold methods in MOLLI sequences (mean difference = − 0.5%, 95% LOA = − 2.9–1.9%).
