Abstract

Cross-sectional modalities or conventional ultrasound are not always able to sufficiently identify and characterize malignant liver lesions. The evaluation of malignant liver lesions in conventional ultrasound relies on echostructure, shape and borders, but often warrants additional contrast-enhanced computed tomography (CT) or magnetic resonance imaging (MRI) studies. Contrast-enhanced ultrasound (CEUS) is a relatively safe imaging technique used for the detection and characterization of malignant liver lesions. The use of a second-generation contrast agent in dynamic real-time imaging allows the visualization of vascularization in any kind of liver lesion as well as liver perfusion during the arterial, portal venous and late phase. Due to the different enhancement patterns, it is possible to differentiate a liver lesion with high diagnostic accuracy (over 90%). CEUS is a helpful complementary technique to cross-sectional imaging for the evaluation of unclear liver lesions and may frequently obviate additional contrast-enhanced MRI or CT studies. CEUS enables the detection and characterization of liver lesions in real time.
