Abstract

BACKGROUND: A 5.0T Cardiovascular magnetic resonance (CMR) offers potential advantages over 3.0T systems, including improved signal-to-noise ratio and spatial resolution. Although myocardial T1 and T2 mapping techniques are increasingly applied in clinical practice, reference ranges for these parameters at 5.0T have not yet been established. The aim of this study is to determine normal reference v…
