Motion artefacts on images acquired with or without CS SENSE. A transverse 2D T2 TSE sequence was acquired; without Compressed SENSE (a-d) and with Compressed SENSE Factor 2 in Fig. 1e, h. In a and b, the volunteer did not move. In c and d, slight head movements from left to right were performed. Motion artefacts visible as semi-circular rings in phase direction left-right were obtained. In e and f, slight head movements from left to right and, in g and h, severe head movements were performed during scanning. The frequency of the motion artefacts visible as semi-circular rings in phase direction left-right was considerably increased from slight to severe head movements
