Representative T1- and R²-maps acquired using conventional diastolic ShMOLLI T1-mapping (TD=500ms/Mx=192) and systolic T1-mapping (TD=0ms/Mx=176). In the normal volunteer (upper panel, normal sinus rhythm), T1 and R² maps have similar appearances and demonstrate near equivalence of T1 and R² values. In a patient with myocardial oedema and sinus tachycardia (lower panel, mean HR 110 bpm), mistriggering of the diastolic T1 map has resulted in underestimation of T1 values and distinctively darker appearance of myocardial tissue on the R² map, whereas systolic T1-mapping circumvented mistriggering with excellent T1 fit on the R² map.
