Phantom images obtained with the BOOST and the conventional PSIR sequence. Imaging data were acquired by nulling the signal from the healthy viable myocardium (blue vial) in the magnitude images (a, e). Differently from f, the T2Prep BOOST dataset, acquired at a high flip-angle, exhibits both high signal from the blood (red vial) and pronounced contrast between blood and healthy viable myocardium (b). The PSIR reconstruction obtained with BOOST and using intensity normalization (d) shows reduced tissue contrast, which is restored once intensity normalization is not applied (c). Furthermore, such restored contrast between the scar tissue (orange vial) and the healthy viable myocardium is comparable to that of the PSIR reconstruction in (g), while improved contrast between scar and blood can be appreciated
