目的:探讨超声造影(contrast-enhanced ultrasound,CEUS)在小肝癌无水乙醇治疗后肿瘤灭活疗效评估中的临床价值。方法:对98例小肝癌患者110个病灶在无水乙醇治疗前后行常规超声和CEUS检查,从病灶大小、边界、内部回声、彩色多普勒血流信号及造影剂灌注情况进行对比分析。结果:CEUS对肿瘤灭活诊断的敏感性、特异性及准确性明显高于常规超声,分别为91.7%、92.3%、91.8%和48.4%、61.5%、50%。结论:CEUS可以作为肝癌恶性肿瘤介入治疗后疗效评估的可靠方法。
Objective: To investigate the clinical value of contrast-enhanced ultrasound (CEUS) in assessing the efficacy of tumor inactivation after small alcoholic liver cancer treatment. Methods: A total of 110 lesions of 98 patients with small hepatocellular carcinoma were examined by conventional ultrasound and CEUS before and after treatment with absolute ethanol. Contrastive analysis was made on the size, boundary, internal echo, color Doppler flow imaging and contrast media perfusion. Results: The sensitivity, specificity and accuracy of CEUS in diagnosis of tumor inactivation were significantly higher than those of conventional ultrasound (91.7%, 92.3%, 91.8% and 48.4%, 61.5% and 50%, respectively). Conclusion: CEUS can be used as a reliable method for assessing the curative effect of interventional treatment of liver cancer.
