Abstract:
Objective To evaluate the value of real-time enhanced-ultrasonography (EUS) in the diagnosis of hepatic tumor. Methods Twenty-nine patients with 34 hepatic solid lesions were examined by real-time EUS,including 16 primary liver malignant tumors,4 metastatic liver tumors,5 focal nodular hyperplasias (FNH),and 9 hemangiomas. All the cases were confirmed by histopathology. The ultrasound unit (Esaote Megas) with real-time EUS technique was used. The contrast agent used was SonoVue (Bracco,Italy). Results After injection of SonoVue,all the lesions were variously enhanced on real-time ultrasonogram. A holistic inhomogeneous enhanced pattern with quick disappearing was mostly detected by real-time EUS in hepatic malignant tumors,a peripheral and centripetal enhanced pattern was mostly shown in hamangiomas,and a radial centrifugal enhanced pattern with homogeneity and quickly was observed in FNHs. If the lesions with enhancement in arterial phase and disappearing in portal phase after injection of SonoVue were regarded as a sign for malignant liver tumor,the sensitivity,specificity and accuracy in the diagnosis of liver cancer with real-time EUS were respectively 95%(19/20),100%(14/14) and 97% (33/34). Conclusions The dynamic enhanced fashions and various enhanced features in various hepatic tumors will be reflected by real time EUS,which improves the accuracy of ultrasonography in the diagnosis of liver tumors.
