超声造影在肝癌早期诊断及射频消融治疗中的应用价值

Value of contrast-enhanced ultrasound in early diagnosis of liver cancer and radiofrequency ablation treatment

肝细胞癌的早期发现及有效治疗对提高患者生存率至关重要。建立简便有效的早期诊断、普查方法及流程,并进行微创有效的治疗,是提高我国肝癌诊治水平的重要课题。介绍了超声造影在肝癌早期诊断及射频消融规范化治疗中的重要作用。叙述了超声造影对肝硬化背景下的小肝癌及其分化程度的判断,以及增生癌变及癌前病变的鉴别诊断。指出超声造影技术在射频规范化治疗以及治疗方案﹑策略制订方面的重要作用,阐明其可应用于射频治疗前、治疗中及治疗后。

Early identification and effective treatment of hepatocellular carcinoma plays an important role in improving survival rate.The establishment of simple and effective procedures for early diagnosis,census methods,and effective minimally invasive treatment is an important project in China to improve the diagnosis and treatment level of liver cancer.Contrast-enhanced ultrasound plays an important role in the early diagnosis of liver cancer and radiofrequency ablation treatment.This article describes how contrast-enhanced ultrasound helps with the identification of small hepatocellular carcinoma and degree of tumor differentiation in patients with liver cirrhosis,as well as the differential diagnosis of hyperplasia/canceration and precancerous lesion.It also introduces the important role of contrast-enhanced ultrasound in standard radiofrequency ablation and development of therapeutic regimens and strategies and clarifies that it can be used before,during,and after radiofrequency ablation treatment.
