Objective: To study the blood supply of hepatic tumors with pulse-inversion harmonic (PIH) imaging and a second-generation contrast agent (SonoVue). The dynamic contrast enhancement and echogenicity of contrast-enhanced ultrasound (CEUS) were recorded and compared with the results of contrast-enhanced CT respectively. The aim was to compare hemodynamics in hepatic tumors using the two technologies, analyze the characteristics of contrast enhancement and blood supply, evaluate their diagnostic value of liver lesions and clinical value in choosing the operation methods and assessing prognosis of hepatic carcinoma.Methods: In this study, ninety-four patients with 46 malignant lesions (12 hepatocellular carcinoma, 2 hepatic adenocarcinoma and 32 metastatic liver tumors) and 48 benign lesions (44 hepatic hemangioma, 2 adenomatous hyperplasia and 2 focal nodular hyperplasia) were examined with PIH imaging after an intravenous administration of SonoVue. All patients were fasting for eight to twelve hours before examinations. At first, 2D gray-scale sonography was used to depict the position, size, outline, inner echo, invade deep, the adjacencies rounding of liver lesions, then transformed to the...
