A cardiac MRF acquisition scheme for simultaneous quantification of myocardial T1, T2 and T in a contrast-free single breath-hold MR scan of ~16s is proposed.
Fig 4: Short axis view of T1, T2 and T quantitative maps in two representative healthy subjects. Reference maps (top row) of T1-MOLLI, T2-GRaSE and T1⍴-Reference are compared against the regularized T1, T2 and T1⍴ cardiac MRF maps (bottom row) obtained from the same ~16s cardiac MRF acquisition.
Fig 5: a) Scatter plots and T1, T2 and T cardiac MRF quantification compared against their reference values obtained from T1-MOLLI, T2-GRaSE and T1⍴-Reference. Green dashed lines depict the identity line. b) Bland-Altman plots of T1, T2 and T cardiac MRF against their respective references. Black lines denote the mean bias and dashed-dotted red lines show the limits of agreement (95% confidence interval).
