T2-weighted TSE is a routine clinical tool for
neuroimaging. TSE generates slightly different contrast
than conventional SE. TSE can also incorporate the
mDixon technique to provide fat/water imaging, but at
the cost of prolonged scan time. In this project, we
propose a spiral SE sequence for enhanced T2 contrast
and fast scan speed. Preliminary results showed
increased T2 contrast with spiral SE in tissues with
increased ion deposition. Its also demonstrated that
the SNR of spiral SE is close to TSE even its scan time
is shorter. Therefore, spiral SE is a potential
alternative to TSE for T2-weighted imaging.
