From: Systolic ShMOLLI myocardial T1-mapping for improved robustness to partial-volume effects and applications in tachyarrhythmias

Fig. 6

Representative T1 and R2 maps acquired using conventional diastolic ShMOLLI T1-mapping (TD 340 ms, normal readout) and systolic T1-mapping (TD 0 ms, short readout) at 1.5 T. In a patient with sinus tachycardia (mean HR range 120–130 bpm) and myocardial oedema post cardiac arrest, mistriggering of the diastolic T1 map resulted in underestimation of T1 values and distinctively darker appearance of myocardial tissue on the R2 map. In contrast, systolic T1-mapping circumvented mistriggering with excellent T1 fit on the R2 map. Normal myocardial T1 by ShMOLLI at 1.5 T is 962 ± 25 ms [10]
