Native T1 mapping is promising non-invasive method for quantitative assessment of diffuse myocardial processes. The aim of the current study was to interrogate normal values for T1 measurement within native myocardium for age and gender using most commonly used sequences and field strengths.
Ninety-nine subjects with no history of cardiovascular or systemic disease or regular medication underwent native T1 imaging with modified (MOLLI; 3,3,5) and shortened modified look-locker inversion recovery sequence (shMOLLI; 1,1,5) at either 1.5T or 3T. The images were analyzed using an Osirix plug-in with manual motion correction of the ROI placed conservatively within the septal myocardium. For comparison, lateral myocardium and blood values were also derived.
MOLLI (septal values)
shMOLLI (septal values)
Gender (septal values)
We report age-gender normal values for native myocardial T1 mapping by the two most commonly used sequences and field strenghts. We show that there are neither gender differences in a cohort as a whole nor within separate age groups.
