Excerpt

Diffuse myocardial fibrosis occurs in various cardiomyopathies and can be indirectly assessed with blood and myocardial T₁ mapping at baseline and after gadolinium administration. The widely used MOdified Look-Locker Inversion-recovery (MOLLI) [1] sequence is known to underestimate myocardial T₁ at higher heart rates, but its dependence on T₂ has not been explored. We investigate MOLLI’s T₁ accuracy in phantoms and confirm with simulations and in-vivo studies. T₁ values are further compared with a saturation-recovery T₁ mapping sequence [2]. …
