Early detection of heart function abnormality by native T1: a comparison of two T1 quantification methods

ConclusionMedian quantification increases the robustness of myocardial native T1 definition, regardless of statistical normality of the data. Compared with the currently prevailing method of mean quantification, differentiation between LV segments and coronary artery territories is better and allows for earlier detection of heart function impairment.Key Points•Median pixel-wise quantification of native T1 maps is robust and can be applied regardless of the statistical distribution of data points.•Median quantification is more sensitive to early heart function abnormality compared with mean quantification.•The new method yields significant native T1 value differentiation between the three coronary artery territories.
