Background: Late gadolinium enhancement (LGE) is well established in assessing myocardial viability on cardiac MRI. Segmented inversion recovery (SIR) is the standard technique used to evaluate scar presence and detect myocardial infarction (MI). However, this technique requires multiple breath-holds and long table time which can be challenging in patients with claustrophobia or dyspnea. Arrhythmia and inadvertent respiratory motion may also induce artifacts affecting overall imaging quality and interpretation. Free-breathing phase-sensitive inversion recovery with respiratory motion correction (PSIR-MOCO) has been used recently and has shown promising results in patients with dyspnea and arrhythmia. In this study, we compare the performance of PSIR-MOCO in assessing myocardial tissue scarring with the standard SIR sequence in a larger cohort of patients with and without myocardial scarring …
