✦ Synopsis
T1 relaxation-time mapping allows direct myocardial signal quantification and therefore enables true quantitative characterisation of myocardial tissue heterogeneity. Differences between healthy myocardium and scarred tissues can be reliably distinguished from the R1 values derived from pre-contrast T1 maps. In patients with scarred tissues, ΔR1 value derived from both the preand the post-contrast T1 maps provides better distinction between grey zone and scar core than either precontrast or post-contrast R1 value alone.
