Obtained from (Duyn et al., 2007). This is an illustration of the image quality of magnitude and phase images obtained at 7T. The GRE data, left and center, had a resolution of 240 × 240 um with a scan duration of 6.5 min, whereas the MP-RAGE data on the right had a resolution of 480 × 480 um and a scan time of 20 min. The scale bar shows the frequency shifts corresponding to the phase changes.
