The diagnostic importance of abdominal ultrasonography has already been well established. In our institution we have carried out abdominal ultrasound and clinically obtained excellent results. In this paper we made ultrasound should diagnosis of hepatomas and studied their visual characteristics. We concluded ultrasound should be a main diagnostic armamentarium to visually diagnose hepatomas. Ultrasound is the most effective screening method of liver tumors and its non-invasiveness is most suitable for the early detection of hepatomas. It is also a very useful method to follow patients suspected of having metastatic liver tumors. We employed both contact scanner and mechanical sector. Contact scan is very appropriate to obtain a whole picture of the liver. Mechanical sector accurately visualizes lesions below right hepatic lobe.
