In this study, we have assessed the image quality and liver lesion conspicuity of a quadruple arterial phase acquisition on the liver obtained in a single breath-hold at 3T using a LAVA FLEX sequence with 32 channel torso coil enabling high parallel imaging capabilities. 42 patients were assessed. Image quality was considered to be good to excellent, and none of the patients had non diagnostic quality study. Artifacts were mostly related to parallel imaging ghosting. Hypervascular lesion conspicuity was best during the 2nd arterial phase.
