Modiﬁed Look-Locker Inversion Recovery (MOLLI) provides the highest precision and reproducibility for myocardial T₁ mapping, and extracellular volume (ECV) mapping. In this work, we determine its effectiveness for measuring myocardial blood flow (MBF), based on apparent-T₁ mapping under two conditions, slice-selective inversion and non-selective inversion. We demonstrate that MOLLI provides measured MBF comparable to the reference FAIR-SSFP ASL method.
