In the
presented study, selective Arterial Spin Labeling and Phase encoded information are obtained in a single acquisition, thereby allowing
for artery-selective velocity and flow imaging. From the data, several image
contrasts can be derived. First, anatomical images are available. From these, static
artery-selective angiograms are obtained, which are processed as binary image
masks and applied to the phase encoded images. Thereby, vessel-selective Phase
encoded angiograms are created. Furthermore, it is possible to calculate
venous-only images by subtraction of the arterial information derived from the
ASL measurements from the phase-encoded images.
