In general, the higher signal-to-noise ratio (SNR) and the better image quality can be
achieved at a higher-magnetic field MRI system. These properties help us to see more detail
structures of the images and identify diseases more clearly in clinical applications. In order to utilize
these advantages, many MRI studies such as fMRI have been performed at higher magnetic field
strength. However, there are also a number of drawbacks such as an increased field inhomogeneity
and the relatively short T2
*. For EPI-based fMRI methods, these issues are the major challenges in
performing the fMRI study. In addition, with EPI-based method, it is difficult to increase the spatial
resolution and correct the artifacts appeared in the images. In order to perform a high-resolution
fMRI at 7T system, this study proposes a high spatiotemporal resolution MRI technique which is
less sensitive to the field inhomogeneity.
