Fast spin echo

Fast spin echo#

A CPMG refocusing train acquires one Cartesian view per echo. Refocusing-angle modulation and view ordering jointly determine the k-space weighting.

Example

Acquisition

Conventional 3D fast spin echo

Fixed optimized train with radial view ordering and its k-space modulation.

Individually optimized 3D fast spin echo

Individually optimized train length, TR, and adaptive radial ordering.

Shuffled echo-resolved 3D FSE

Variable-density shuffled sampling for echo-resolved reconstruction.
