T2* maps are used in many applications from functional
brain imaging to targeted contrast agents. However,
in-plane magnetic field inhomogeneity leads to a
non-exponential decay of the T2* signal. This work
proposes a method to estimate T2* by taking into account
intra-voxel magnetic gradients. A k-space estimation
approach is developed, combined with a single shot
multi-echo spiral out trajectory.
