In this work a compressed sensing (CS) accelerated 3D
phase encoded turbo-spin echo (3D-PE-TSE) sequence was
used to obtain geometrically undistorted images in the
presence of titanium in a clinically acceptable time
frame (<10min). By ordering the acquired echos in
spherical layers with an equal number of sampling points
it was possible to combine TSE and CS acceleration to
achieve a factor 60 scan time acceleration compared to a
3D-PE-SE scan. Phantom and in vivo results confirm that
the presented method can be used for investigations
where spatial accuracy is required.
