The role of contrast-enhanced ultrasound in the characterisation of focal liver lesions

Introduction: Contrast-enhanced sonography is a useful tool for evaluating the vascularity of liver tumors, because it allows visualization of the blood perfusion. Moreover, the method is simple, easy, and minimal invasive, being usually performed on an out-patient basis. Aim: The objective of this study was to evaluate the liver masses using microbubble contrast-enhanced sonography (using a second generation contrast agent). Subjects and methods: Thirty lesions were evaluated with dynamic contrast harmonic imaging in wideband pulse inversion mode comprising 22 malignancies (14 hepatocellular carcinomas, 8 metas…
