Various segmented 3D acquisitions have been developed
for Arterial Spin Labeling. Conventional spiral TSE ASL
uses a spiral-out readout to collect data on a stack of
spiral trajectory. So not only the spin echo is not
aligned with the center of k-space, but it also requires
the number of slices be equal to (or a multiple of) ETL.
Here a 3D spiral TSE sequence is proposed by employing a
spiral-in/out readout on a distributed spiral
trajectory. The preliminary results demonstrate that the
proposed technique can produce comparable or better
image quality when compared to 3D GRASE ASL.
