PurposeTo develop and evaluate a wideband arrhythmia‐insensitive‐rapid (AIR) pulse sequence for cardiac T1 mapping without image artifacts induced by implantable‐cardioverter‐defibrillator (ICD).
MethodsWe developed a wideband AIR pulse sequence by incorporating a saturation pulse with wide frequency bandwidth (8.9 kHz) to achieve uniform T1 weighting in the heart with ICD. We tested the performance...
Both post‐contrast myocardial T1 and extracellular volume (ECV) measurements have been associated with diffuse interstitial fibrosis. The cardiovascular magnetic resonance (CMR) field is migrating towards ECV, because it is largely insensitive to confounders that affect post‐contrast myocardial T1. Despite the theoretical advantages of myocardial ECV over post‐contrast myocardial T1, systematic experimental...
