目的:探讨实时灰阶超声造影(contrast-enhanced grey-scale ultrasonography,CE-US)在肝癌介入治疗后疗效评价中的应用价值。方法:经肘前浅静脉团注超声对比剂SonoVue,观察各时相病灶的强化特点,并与治疗前CE-US、治疗后CT、MRI图像及随访结果进行比较,综合判断介入治疗效果。结果:CE-US可以清晰地显示病灶内有无局部或整体强化,能准确评价肝癌介入治疗后疗效。结论:CE-US在评价肝癌介入疗效时具有重要的临床价值。
Objective: To investigate the value of real-time gray-scale contrast-enhanced ultrasonography (CE-US) in evaluating the curative effect of interventional therapy of liver cancer. Methods: Ultrasound contrast agent SonoVue was injected into the superficial vein of the elbow to observe the enhanced features of each time-phase lesion, and compared with the CE-US before treatment, CT and MRI images after treatment and the follow-up results to judge the effect of interventional therapy. Results: CE-US can clearly show the lesion with or without local enhancement, can accurately evaluate the efficacy of interventional treatment of liver cancer. Conclusion: CE-US has important clinical value in assessing the therapeutic effect of liver cancer intervention.
