3D PROPELLER-Based Diffusion Weighted Imaging

Eric Aboussouan¹, Jim Pipe¹

A new sequence dubbed TURBINE (TURBoprop IN Elevation) is proposed which adapts the Turboprop scheme to 3D DWI imaging. The trajectory is based on a Turboprop sequence where the gradient echoes are placed in the slice encoding direction. Benefits over EPI and Turboprop include higher SNR efficiency, lower SAR and MTS, reduced off-resonance artifacts and 3D phase correction.
