Data are mean ± SD unless otherwise indicated.
*At 20 minutes post gadolinium administration.
λ, Myocardial partition coefficient (Lambda); ECV, Extracellular myocardial volume; LGE, Late gadolinium enhancement; STIR, Short Tau inversion recovery.
For postcontrast T1, λ and ECV, the number of SSc patients included in the analysis is 14 rather than 19.
