Table 1.
T1 accuracy measured in a phantom experiment using the proposed LGE/T1 sequence, defined as the absolute difference of the mean T1 time in each vial and the spin-echo reference, averaged over ten repetitions. The proposed sequence was performed with different inversion-times in the LGE image, resulting in nulling of the different vials. Each sequence was repeated 10 times. The reference T1 times, assessed with an inversion recovery spin-echo sequence are given in parentheses.
