Conventional contrast-enhanced 3D T1w hepatic imaging requires serial breath-hold acquisitions to capture the contrast dynamics, inherently limiting spatial resolution and image quality. The hepatobiliary-specific contrast agent Gd-EOB-DTPA offers a prolonged time window of contrast-enhancement over which data can be acquired. This work evaluates the clinical feasibility of using a navigator-gated 3D T1w sequence to improve the spatial resolution and image quality of Gd-EOB-DTPA-enhanced hepatobiliary imaging compared to conventional breath-hold imaging.
