Myocardial T₁-mapping at 3T using saturation-recovery: reference values, precision and comparison with MOLLI.

ABSTRACT:

Background

Myocardial T₁-mapping recently emerged as a promising quantitative method for non-invasive tissue characterization in numerous cardiomyopathies. Commonly performed with an inversion-recovery (IR) magnetization preparation at 1.5T, the application at 3T has gained due to increased quantification precision. Alternatively, saturation-recovery (SR) T₁-mapping has recently been introduced at 1.5T for improved accuracy. Thus, the purpose of this study is to investigate the robustness and precision of SR T₁-mapping at 3T and to establish accurate reference values for native T₁-times and extracellular volume fraction (ECV) of healthy myocardium.
