Impact of age, heart rate, and body surface area on myocardial native T1, T2, and extracellular volume fraction in pediatric patients at 1.5 Tesla cardiac magnetic resonance imaging.
BACKGROUND Cardiac magnetic resonance (CMR) enables the quantitative characterization of myocardial tissue through parametric myocardial tissue mapping. It shows a strong correlation with invasive histologic techniques in assessing diffuse myocardial fibrosis using native T1 mapping and extracellular volume (ECV), as w...
