Sequence simulations and phantom images comparing BOOST and conventional sequences for LGE assessment and CMRA. Simulated magnetization of the post-contrast BOOST sequence (a, b), of a conventional PSIR sequence (f, g), and of a dedicated post-contrast CMRA sequence (k, l) are displayed. The expected longitudinal magnetization (Mz/M0) is reported for blood (red lines), healthy viable myocardium (blue lines), and scar tissue (orange lines). Furthermore, results from the phantom experiments are displayed (BOOST: c, d, e; PSIR: h, i, j; CMRA: m) and the vial of interest are highlighted (blood – red circle, healthy viable myocardium – blue circle, and scar tissue – orange circle). Comparable contrast between the scar tissue and healthy viable myocardium can be observed in the PSIR reconstructions obtained with the BOOST sequence (PSIR BOOST) and the conventional PSIR sequence. Differently, improved contrast between the scar tissue and the healthy viable myocardium can be observed in the PSIR BOOST dataset when compared to the conventional PSIR sequence (phantom images in e and j). Data acquired with BOOST at even heartbeats (T2Prep BOOST, d) exhibit higher signal when compared to the reference image of the conventional PSIR sequence, acquired at a low flip-angle (i). In particular, T2Prep BOOST shows comparable signal and tissue contrast to that of a dedicated T2 prepared CMRA sequence (m)
