The ability to create clinically relevant image contrasts in continuously moving table (CMT) imaging is a pre-requisite to enable applications such as metastases screening in cancer patients. In this paper, feasibility of contrast manipulations for 3D CMT imaging is studied, which requires special attention with respect to the timing of the preparation pulses and the type of segmentation to avoid table-motion induced image artifacts. Different magnetization preparations and k-space segmentations were studied in experiments on healthy volunteers showing a robust image quality.
