Contrast-enhanced US (CEUS) has an important role as a supplement to CT or MRI in
clinical practice. The main established utilizations are in the liver and the kidney. The …

Objective We assessed the usefulness of contrast-enhanced ultrasound (CEUS) in the
differentiation of intrahepatic cholangiocarcinoma (ICC) and hepatocellular carcinoma …

The recent design of ultra-broadband, multifrequency ultrasound transducers has enabled
high-sensitivity, high-resolution contrast imaging, with very efficient suppression of tissue …

More and more asymptomatic benign liver tumours are discovered incidentally and can be
divided into regenerative lesions and true neoplastic lesions. The most common …

Accurate characterization of cirrhotic nodules and early diagnosis of hepatocellular
carcinoma (HCC) are of vital importance. Currently, computed tomography (CT) and …

OBJECTIVE. The objective of our study was to determine the role of negative enhancement
(washout), its presence and timing, in the differential diagnosis of hypervascular liver …
