Fig. 7:

Visual comparison of the whole-heart data recovered by SToRM:Two-Step against breath-held CINE data. (i) First two rows show the Cartesian SSFP based breath-held results. (ii) Second two rows show the GRE based SToRM:Two-Step reconstruction results. The increased TR and flip angle allows us to get improved GRE contrast, resulting from the inflow enhancement of the LV blood pool. The end-diastole frames are shown across all slices. Most slices of SToRM:Two-Step reconstruction show good agreement with breath-held images in terms of image quality. We stress that the direct comparison of the two methods is challenging since the two sequences differ significantly in several aspects, including image contrast and bias fields; it is difficult to draw a strong conclusion on the equivalence between the two methods, beyond the limited qualitative comparisons in Table II.
