Abstract:
Objective To compare enhancement features of hepatic tumors on SonoVue-enhanced real-time gray-scale ultrasonography and contrast-enhanced helical CT.Methods SonoVue-enhanced real-time gray-scale ultrasonography and contrast-enhanced helical CT were performed on 49 patients with 54 focal liver lesions,including 29 primary liver carcinomas,4 metastatic liver tumors,11 hepatic carvernous hemangiomas,7 focal nodular hyperplasias,2 focal fatty sparing,1 cirrhotic.Results Contrast-enhanced ultrasonography and helical CT showed consistent results in demonstrating hemodynamics of hepatic tumors.In the differentiating of malignant tumors and benign tumors,the sensitivity,specificity and accuracy of contrast-enhanced ultrasonography were(90.9)%(30/33),(90.5)%(19/21) and(90.7)%((49/54)),respectively.Those of contrast-enhanced CT were(90.9)%(30/33),(95.2)%(20/21) and(92.6)%((50/54)),respectively.Conclusions Both of the two imaging methods are valuable for differential diagnosis of liver tumors.
