Sequence-specific ECV thresholds are required in animal models; leaves open validation and human translation before clinical adoption.
Does AIR cardiac T1 mapping yield different myocardial T1 and ECV measurements compared to MOLLI in animal models?
MOLLI and AIR pulse sequences yield significantly different T1 and ECV values, indicating that ECV cutoff values are sequence-specific and cannot be directly translated between different T1 mapping techniques.
