The purpose of this study was to explore the efficacy of multiarterial phase dynamic MR imaging of the whole liver using LAVA (Liver Acceleration Volume Acquisition) at 3T to depict small early enhanced hepatic lesions as well as hepatic arterial system. Nine patients with small early enhanced hepatic lesions were included in the study. Multiarterial phase (four phases) imaging of the whole liver during a single breath-hold was performed. Diagnostic quality images were obtained. Early enhanced hepatic lesions and main branches of portal veins were depicted as well as hepatic arterial system on the MIP images of subtraction. The contrast-enhancement dynamic process of small early enhanced hepatic lesions and their relationships with the hepatic vascular systems can be well depicted with increased spatial and temporal resolution.
