摘　　要：本文对２２例原发性肝癌患者（共４６个肝癌结节）进行了二氧化碳肝动脉超声造影和常规超声法对照分析。其中直径＞３ｃｍ的肝癌灶２４个，直径≤３ｃｍ的肝癌灶２２个。研究表明，超声造影对检出直径＞３ｃｍ的肝癌灶的敏感性比常规超声略高，但二者之间无统计学差异；而对直径≤３ｃｍ的肝癌灶，超声造影检出的敏感性显著高于常规超声（Ｐ＜０．０１）。我们认为，二氧化碳肝动脉超声造影对检出常规超声未能显示的小肝癌甚有价值。CO2-HAS and conventional ultrasound in the detection of primary liver cancer (PLC) were comparatively studied in twenty two patients with forty-six cancer nodules proved by operation,X-ray angiography, CT, and/or CTA, among which twenty-two nodules were smaller than or equal to 3 cm in diameter, the other twenty-four were larger than 3 cm in diameter. The results demonstrated that the sensitivity for diagnosis of primary liver cancer larger than 3 cm in diameter with CO2-HAS was slight higher than those .of conventional ultrasound (P>0. 05). Whereas the sensitivity in small liver cancer group. (nodules small than or equal to 3 cm in diameter) was significantly higher with CO2-HAS technique than those with conventional ultrasound (P<0. 01). The CO2-HAS technique has thought to be a more valuable tool in the detection of small primary liver cancer which couldn't be detected with conventional ultrasound.
