In this study, we show larger dynamic range of hepatic T2* values using a high-performance 0.55T, compared to 1.5T, which may be valuable to stratify patients with severe iron overload.
Figure 4: T2*-weighted images (TE= 10.3ms) and T2* maps from 0.55T and 1.5T.
Figure 3: Liver T2* measured at 0.55T and 1.5T in patients with iron overload (n = 34). The blue box highlights patients with moderate to severe iron overload with T2*<3ms at 1.5T. Larger dynamic range at 0.55T for patients with severe iron overload was observed.
