Dynamic
contrast-enhanced (DCE) 3D T1w MRI is routinely used in abdominal imaging for
characterization of liver lesions. Each contrast-enhanced phase is typically
acquired within a breath-hold; however, this multi-breath-hold requirement
faces several drawbacks. In this work, navigator gating is combined with
adaptive navigator correction (slab following) to prospectively adjust slab
location based on measured motion, with the goal of improving the image
quality and acquisition efficiency of navigated 3D DCE liver imaging. Initial
contrast-enhanced clinical results with this method are presented.
