| Zusammenfassung | The aim of this work is to develop and investigate an accurate sequence for MR flow quantification. We utilized a 3D ultra-short echo time (UTE) flow sequence to minimize the displacement artifact that frequently occurs in MR flow imaging. In UTE acquisitions, the position is encoded at the beginning of the readout. Thus, the time difference between velocity encoding and spatial position encoding is minimized. This leads to an improved accuracy of the velocity quantification. The sequence was tested and validated against a reference sequence and a conventional 4D flow sequence in a flow experiment in vitro at 3T. |
