In
a high field MRI, improvements in SNR and image quality are very noticeable,
even though there are some drawbacks such as increased field inhomogeneity
and relatively short T2*. For EPI-based methods, these
drawbacks are major challenges in performing fMRI. To reduce such problems,
we employed the HGS-Parallel technique as an fMRI imaging method which used
the conventional gradient echo. This sequence is relatively robust to field
inhomogeneity and the T2* decay than the EPI. With the
HGS-Parallel technique, we performed an fMRI experiment at a 7T for mapping
the finger somatosensory area in a high quality and resolution form.
