Excerpt
Cardiac fibrosis is a known marker of adverse remodeling of the heart. Late-gadolinium-enhanced (LGE) T1 mapping is the only proven method to assess diffuse myocardial fibrosis. The most widely used LGE cardiac T1 mapping pulse sequence is MOLLI, which is based on inversion-recovery (IR) magnetization pre-conditioning and Look-Locker imaging. Unfortunately, MOLLI is sensitive to heart rate and rhythm and T2 effects and requires a long breath hold duration. We present an arrhythmia-insensitive, rapid (AIR) cardiac T1 mapping pulse sequence which is also insensitive to T2 effects. …
