目的 评价肝肿瘤指标和肿瘤血管分布模式在鉴别肝恶性肿瘤方面的价值。方法 对113个肝恶性肿瘤进行彩色及脉冲多普勒显像,观察肝血流模式,计算肝肿瘤指标(肿瘤血管血流速度峰值/同侧肝动脉的血流速度峰值)。结果 原发性肝癌和肝转移癌的肝肿瘤指标分别为1.12±0.36、0.62±0.21,二者有显著差异(P<0.01);原发性肝癌血流模式多呈“提篮”型和肿瘤内血流,而肝转移癌多见肿瘤外围绕行的血流。结论 彩超上用肝肿瘤指标鉴别原发性肝癌和肝转移癌是有价值的,原发性肝癌血流模式有一定特征,但特异性有限。
Objective To evaluate the value of liver tumor markers and tumor blood vessel distribution patterns in the differential diagnosis of hepatic malignancies. Methods Color and pulsed Doppler imaging were performed on 113 hepatic malignancies. Hepatic blood flow patterns were observed and hepatic tumor indices (peak blood flow velocity in the tumor/peak blood flow velocity in the ipsilateral hepatic artery) were calculated. Results Liver tumors of primary hepatocellular carcinoma and hepatic metastasis were 1.12±0.36 and 0.62±0.21, respectively. There were significant differences between the two groups (P<0.01). The blood flow patterns of primary hepatocellular carcinoma were mostly “basket” type and intratumor. Blood flow, and hepatic metastases are more common in the blood flow around the tumor. Conclusion It is valuable to identify primary hepatic carcinoma and hepatic metastasis with liver tumor markers on color Doppler ultrasound. The blood flow pattern of primary hepatic carcinoma has certain characteristics, but the specificity is limited.
