Figure 2

Transverse 2D LGE acquisitions in a patient with fast AF both with (left) and without (right) the dynamic_TI algorithm. The sequence repeat intervals throughout the acquisitions are also shown (middle), together with simulations of the longitudinal magnetisation (as a % of M0) for the central phase encode lines in each data segment. The average RR interval for this subject was ~500ms but missed triggers resulted in the average sequence repeat time interval being ~700ms in both cases. The dynamic_TI algorithm results in reduced longitudinal magnetisation variation throughout the acquisition and consequently, much better image quality.
