Spine is a challenging area for MRI due to both anatomical features and motion. Spiral TSE has been proposed for spinal MRI. Aliasing in spiral spinal MRI is mitigated by combining oversampling with saturation band, with the latter not always achieving consistent and good signal suppression. In this work, the ZOOM technique has been incorporated into spiral TSE. Phantom and in vivo results demonstrate better signal suppression with ZOOM spiral TSE compared to spiral TSE acquired with a saturation band.
