To determine whether a method that improves temporal resolution via a combination of parallel imaging and temporal view sharing improves the capture of gadoxetate arterial phase after the administration of gadoxetate disodium. 37 patients were imaged with a conventional technique and 48 patients were imaged with the accelerated technique. A multiphase acquisition included the arterial phase more frequently than the conventional acquisition, with 17% of patients imaged with conventional acquisition missed the arterial phase compared to 2% with the multiphase acquisition. Additionally, there was increased relative intensity of the hepatic arteries and improved lesion enhancement with respect to adjacent parenchyma.
