Previous studies have shown that T1w SE POPELLER is helpful in the reduction of flow artefacts in the brain, especially in the T1w images post-Gd. An additional advantage of SE-PROPELLER sequence is the possibility to reduce bulk motion artefacts. In this study, the effects of the PROPELLER readout are evaluated in the neck region in patients with head and neck tumors, which is usually degraded by motion and flow artefacts. In this work we have shown that with T1w SE-PROPELLER, motion artefacts can be reduced significantly. Flow artefacts in T1w scans are also minimized in the SE PROPELLER.
