平行的

Seven cases with portal vein tumor thrombus were diagnosed by CO2-hepatic arterio-sonography (CO2-HAS). Their ultrasonographic features of CO2-HAS were as follows: several seconds after the injection of CO2 microbubble contrast, bright cloudy flowing echoes or several flowing echo stripes along the long axis of portal vein were seen in tumor thrombus. During interrupted phase of CO2 contrast injection there were still scattered unflowing bright echoes in tumor thrombus.

应用二氧化碳(CO2)肝动脉造影诊断 7 例门静脉癌栓，其造影增强声像图表现为：注射CO2微泡造影剂数秒钟后即可见癌栓光团弥漫性光点闪动，似白云翻滚或门脉实体回声内有数条和门静脉管径长轴平行的微气泡光带流动，停止注射后门静脉实体回声内仍有弥漫性非流动性增强光点，持续时间较长。
