Zusammenfassung
The separation of portal-venous and hepatic arterial blood supply is important for the evaluation of chronic liver diseases and the characterization of liver lesions. The aim of this study was to investigate the capability of a pseudo-continuous arterial spin labeling sequence, to separate arterial and portal venous perfusion of the liver using a background suppression technique and different tagging plane orientations. It was demonstrated that the presented method provides high quality perfusion images of the liver without application of intravenous contrast agent and offers promising approaches for the separation of arterial and portal-venous perfusion fractions.
