The recent dual-echo arterial spin labeling (DE-ASL)
technique has been proposed for the simultaneous
acquisition of cerebral blood flow and blood oxygenation
level dependent (BOLD) responses to brain activation. In
order to compare the performance of DE-ASL and
conventional BOLD-fMRI sequences for identifying regions
involved in active and imagery movement, single-subject,
group and statistical analysis were computed on a group
of volunteers. DE-ASL has shown to be suitable for
mapping brain functions as well as the fMRI-BOLD both
during the movement task and during the imagination of
the movement.
