| 摘 要： | 通过１３只接种Ｗａｌｋｅｒ－２５６瘤株的鼠肝癌模型进行经门静脉的ＣＯ２增强超声造影的研究．超声造影结果显示，肝内呈弥漫性增强，持续较长时间，肝肿瘤显示为低回声区，边界清晰，呈负性增强。说明肝肿瘤缺乏门静脉血供，但ＣＯ２超声增强仍能提高超声对鼠肝肿瘤的显示率。本研究对鼠肝肿瘤的检出率为１００％，显著高于常规超声（１８．２％）。最小的鼠肝肿瘤仅３ｍｍ，超声所测的肿瘤大小与肿瘤标本的大小有显著的相关性。因此，门静脉ＣＯ２超声造影对提高小肝癌的检出有很大的帮助。

| Abstract: | CO2 enhanced ultrasonograPhy (CO2-EUS) via Portal vein for detecting experimental hepatic tumor was performed in 13 rats. After CO2 injection, the whole liver was shown enhanced diffuse echoginicity, which lasting a long time, and liver tumor was relatively shown a hypoechoic region,which suggesting lack of blood supply of portal vein in the tumor The detection rate of CO2-EUS (100%)for liver tumor was much higher than that of conventional US(18.2%).The minimal diameter of tumor detected by CO2-EUS was 3 mm . Therefore,CO2-EUS via portal vein was helpful in the detection of small liver tumor. |
