PRIMARY OBJECTIVES:
I. Determine the accuracy of contrast enhanced ultrasound (CEUS) utilizing contrast agent sulfur hexafluoride lipid-type A microspheres compared to B-mode non-contrast enhanced ultrasound for liver lesion detection, including hepatocellular carcinoma (HCC), in cirrhotic ultrasound (US) patients.
SECONDARY OBJECTIVES:
I. Determine the concordance of CEUS vs. contrast enhanced magnetic resonance imaging (CE-MRI) Liver Imaging Reporting and Data Systems (Li-Rads).
OUTLINE:
Within 30 days of routine MRI, participants undergo non-contrast ultrasound of the abdomen. Participants then receive Lumason intravenously (IV) and undergo contrast-enhanced ultrasound of the abdomen over 1 hour.
