原发性肝癌实时谐波超声造影

目的:探讨原发性肝癌实时超声谐波造影时间窗及动脉早期初始强化形式及意义.方法:观察完整时相,确定时间窗.分析初始强化形式以及该形式与二维图像、CDFI的关系.结果:93.4%(44/47)表现为"快进快出"特征.边界不清的病灶中10例造影后较造影前增大.肝癌病灶在超声造影中开始强化表现具有不同形态学特点.结论:原发性肝癌超声造影有自己的"时间窗".将超声增强初始强化表现与二维图像、CDFI相结合,有助于判断肿瘤的病理类型及生物学行为.

Clinic study on the time-window and the expression of early enhancement about real-time harmonic contrast-enhanced ultrasound of primary hepatocellular carcinoma

Objective To investigate the expression and application value of the time-window and expression of early enhancement about real-time harmoniccontrast-enhanced ultrasound in primary hepatocellular carcinoma. Methods Whole phase manifestation was observed to determine the time-window and to analyse the early enhancement forms and the relationship between enhanced image and B-mode image and CDFI. Results Forty-four cases (93. 4%) showed "fast-in and fast-out" , 10 cases of marginal unclear showed larger after enhanced. The various morphology features appeared in the early enhanced of hepatocellular carcinoma. Conclusion There is the time-window in ultrasound contrast-enhanced about hepatocellular carcinoma. It is useful to assess the pathology type and biological behavior of the tumor by combine the enhanced image features with B-mode image and CDFI.
