Characterization of focal liver lesions remains a diagnostic challenge for the radiologists, more so when there is associated underlying chronic liver disease (CLD). Imaging plays a vital role and there has been a constant endeavor to improve the diagnostic accuracy of liver lesions. The introduction of mutiphasic CT and MRI has revolutionized the diagnostic ability of liver lesions. With the advent of ultrasound contrast agents (UCAs), it is possible to evaluate liver lesions using the non-invasive imaging technique of “contrast-enhanced ultrasonography” (CEUS).1-3 CEUS can overcome the limitations of grey scale and color doppler sonography4,5 and has been used for characterisation of focal liver lesions.2. It can depict arterialisation of hypervascular hepatocellular carcinoma (HCC)6,7 and can also help in assessment of the post-therapeutic response.8,9 We present two such cases of HCC evaluated by a recently available second generation ultrasound contrast agent, SonoVue (Bracco, UK).
