Figure 7

T1-maps acquired at different center frequencies using MOLLI 5s(3s)3s at 3 T. Despite the use of a 2nd order shim in a local volume around the heart, off-resonance variation across the heart, as seen in the field map (left), leads to an artifactual local variation in the apparent T1 as indicated by arrows [42].
