Dynamic 3D Contrast Enhanced Liver Imaging Using a Novel Hybrid Cartesian-Radial Acquisition with Flexible Temporal and Spatial Resolution

Pascal Spincemaille¹, Beatriu Reig¹, Martin R. Prince¹, Yi Wang¹

High temporal resolution dynamic contrast enhanced liver imaging is achieved using a novel k-space sampling method that samples the phase and slice encoding plane along true radial trajectories with an angularly varying field-of-view and resolution. Combined with an adapted golden ratio view order, it eliminates the need for accurate bolus timing and allows the retrospective selection of the optimal arterial enhancement for the detection and characterization of liver lesions.
