In
this work, high temporal resolution 4D dynamic contrast enhanced liver MR
imaging is achieved using a stack of spirals trajectory and sliding window
reconstruction in healthy volunteers. This allows the detection and
characterization of liver lesions in the arterial and later phases without
the need for accurate contrast bolus timing. Additionally, a retrospective
selection of the optimal arterial phase is possible and the determination of
hepatic artery anatomical variants can be done with increased diagnostic
confidence.
