Doppler ultrasonography of hepatic artery in malignant liver tumors
نویسنده
چکیده
INTRODUCTION Doppler ultrasonography enables non-invasive hemodynamic investigation of portal circulation. Doppler examination offers significant information on artery flow velocity waveforms in splanchnic arteries (hepatic artery) of the abdominal organs. Normal arterial flow of these arteries is anterograde both in systole and diastole (biphasic flow), which indicates small flow resistance (Figure 1).

The aim of this study was to try to diagnose malignant liver lesions and hemangiomas by means of vascularisation and perfusion studies. The study was performed in 32 patients with hepatocellular carcinoma (HCC), in 74 with metastatic liver carcinoma (MLC) and in 40 with hemangiomas (H). Color Doppler ultrasonography (DUS) was done with an ATL Ultramark 9 apparatus with convex probe 2.5 MHz usin...
