This work shows that high resolution (0.5 mm isotropic) T2* weighted images of the whole brain can be obtained in less than 6 minutes by utilizing the high SNR efficiency of echo planar imaging (EPI). The image SNR is increased by a factor of 2, and the coverage by a factor of approx. 5, compared to conventional gradient echo imaging (GRE) with the same scan duration. The contrast for both magnitude and phase is equivalent between EPI and GRE imaging.
