To show the usefulness of contrast-enhanced ultrasonography (CEUS) before,
and after percutaneous treatment of hepatic tumors,
with special emphasis on hepatocellular carcinoma.
Ultrasound contrast agents contain microbubbles that increase the signal after they are administered into the bloodstream or into a body cavity.
To evaluate the liver,
the most common ultrasound contrast agent is sulfur hexafluoride stabilized with different surfactants (phospholipids and palmitic acid),
commercialized under the name SonoVue® and administered intravenously.
The microbubbles are similar to or smaller than red blood cells in size (1-10 µm),
allowing them to circulate through...

USEFULNESS OF CEUS BEFORE PERCUTANEOUS TREATMENT: 1) Characterization of focal lesions in ultrasound screening for hepatocellular carcinoma: CEUS is included in LIRADS®,
the internationally recognized guidelines for the standardization of diagnostic imaging for hepatocellular carcinoma.
Observations are classified into 8 categories ( Fig. 2 ) : CEUS LR-NC: cannot be categorized due to image degradation or omission CEUS LR-1: definitely benign Cyst: anechoic lesion with increased posterior...
CEUS is useful for locating and characterizing focal liver lesions before treatment,
for guiding percutaneous ablation during the procedure,
and for evaluating the response to treatment and detecting complications after ablation.
