肝细胞癌CT增强与超声造影强化模式的对比研究

目的通过观察肝细胞癌CT(MSCT)增强与超声造影影像,探讨二者强化模式的差异。方法对经手术切除的15例肝细胞癌患者进行MSCT增强与超声造影检查。结果10例肝细胞癌的MSCT增强扫描与超声造影强化模式相似,表现为"高—低—低"模式;5例肝细胞癌的MSCT增强扫描和超声造影影像强化模式不完全相同。结论肝细胞癌的MSCT增强与超声造影强化模式存在着一定的差异,这可能是由不同类型造影剂的生物学分布特征以及肿瘤内门静脉参与供血所造成的。

Objective To evaluate the differences in enhanced modes of hepatocellular Carcinoma between by enhanced CT and by contrast- enhanced ultrasound. Methods 15 patienets with hepatocellular Carcinomas were examined both by enhanced CT and by contrast-enhanced ultrasound. Results The enhanced modes of 10 cases were similar by these two methods, showed as ＂high-low-low＂ mode. But in other 5 cases, there were some differences between them. Conclusion There were some differences in hepatocellular Carcinoma images both by enhanced CT and by contrast-enhanced ultrasound, maybe because of the different distribution of two contrast agents in the tissue and blood supply to tumors by portal vein.
