Purpose To develop a single‐scan method for B1+‐corrected T1 mapping and apply it for free‐breathing (FB) cardiac MR multitasking without electrocardiogram (ECG) triggering. Methods One dual flip‐angle (2FA) inversion recovery (IR)‐FLASH scan provides two observations of T1∗ (apparent T1) correspond...
