To achieve SWI based on susceptibility maps without
streaking artifacts in short calculation time, a method
was developed for susceptibility-weighted imaging using
a susceptibility map calculated without regularization
in very small iteration number. To evaluate the
usefulness of the proposed method, image contrasts of
axial slices in closed-type MRI and open-type MRI
acquired by the conventional and the proposed method
were compared. The results suggest that the proposed
method can enhance contrast of regions with high
magnetic susceptibility, such as veins or iron
depositions, in arbitrary slice orientation within about
20 seconds without streaking artifacts.
