Simultaneous
quantification
of T2 and T2* within
1 minute
using
improved
10-echo GESE-EPIK is
validated for phantoms
and in
vivo
with reference methods. Successful
WM/GM separation is
shown. Sequence acceleration
is
investigated
with
(t)SNR
analysis.
Figure 4: In
vivo
relaxation
quantification results. One exemplary slice for T2 and T2* maps from
GESE-EPIK and the reference methods is shown in the top left corner.
T2*
and T2
histograms from
all acquired slices
compare
each parameter distribution from GESE-EPIK with its reference method.
Mean values of each distribution with its standard deviation are
given.
Figure 2: Reconstructed
images from 10-echo
GESE-EPIK for four exemplary slices of an in
vivo
data set. The
TE
for each echo is
given. The
signal
strength of later echoes is modulated for visualisation
purposes.
