| 目的 探讨彩色多普勒血流成像(CDFI)及高频超声对肝实性病灶的诊断价值。方法 对73个肝脏实性病灶进行超声检查,记录肝脏背景及血流情况。结果 高频超声可更细致地观察靠近肝脏表面病灶(<7 cm)内部的回声特点。小肝癌中80%可检测到动脉供血,60%有门静脉供血,46.7%为肝动脉及门静脉双重供血。2例发育不良结节可检测到门静脉供血。结论 高频超声及CDFI可为肝实性病灶提供重要的鉴别诊断信息。肝硬化或慢性肝炎患者发现肝内实性低回声病灶,应警惕恶性可能。 |

| Objective To evaluate color Doppler flow imaging (CDFI) and high frequency ultrasound in the diagnosis of solid liver lesions. Methods Total 73 solid liver lesions were examined by CDFI and high frequency ultrasound. The liver parenchyma, echo characteristics of the lesion and its flow distribution were recorded. Results All 15 small hepatocellular carcinoma (sHCC) developed in the patients with chronic hepatitis or cirrhosis. The internal characteristic of lesions adjacent to the liver surface could be observed more precisely than those located deeper on high frequency ultrasound. Blood supplied by the artery was in 80%, by portal vein in 60%, and double supply in 46.7% in the patients with sHCC. Portal vein supply was observed in 2 dysplastic nodules (2/4, 50%). Conclusion CDFI and high frequency ultrasound may provide valuable diagnostic information of solid liver lesions. Special attention to possibility of malignancy should be taken on the solid lesions in the patients with chronic hepatitis or cirrhosis. |
