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.
