抄録

By means of pulsed Doppler method, tumor blood flow of 79 hepatocellular carcinomas was studied. The waveforms of Doppler signals were divided into three types: high-speed pulsatile waveform (8 tumors), low-speed pulsatile waveform (43) and continuous waveform (60). In relation to the tumor size, detection rate of Doppler wave increased from 66.7 to 100% as the size increased. The speed of tumor blood flow also gained as the size increased.<BR>Comparative study of blood flow by Doppler method and hepatic angiography revealed three relations such as high-speed pulsatile wave and arterio-portal sbunting, low-speed pulsatile wave and tumor vessels, and continuous wave and tumor stain. In conclusion, pulsed Doppler method may be a useful technique in study of tumor blood flow in detail.
