Abstract
A magnetic resonance imaging (MRI) system and method for controlling the MRI system is provided. The method includes directing the MRI system to perform a pulse sequence that includes generating a RF excitation pulse to excite spins in slice locations within a selected slab to produce an echo train from the slab that is formed by a plurality of echoes. The sequence also includes applying a slice-encoding gradient to spatially encode echoes associated with a different slice in the slab, and applying readout gradients during the echo train to acquire MR data from the slab, the readout gradients including a first sampling strategy defining a spiral-in k-space trajectory and a second sampling strategy defining a spiral-out k-space trajectory, wherein the MRI system is directed to repeat the sequence such that a plurality of subsequent selected slabs are excited and MR data is acquired therefrom.
