目的:讨论运用Sono Vue进行超声造影与常规超声相比较,在提升鉴别肝脏肿瘤良恶性的应用。方法:对78例采用常规超声检出肝脏局灶性病变((FLL)的病人进行回顾性分析,依据彩色与二维多普勒的特点,在综合病人的病史得出初步判断良恶性以后,再对其进行超声造影,分析病灶造影剂灌注过程,来修正初步判断;最后金标准为病理结果,用统计学进行分析。结果:病理结果表明78个病灶中,恶性病灶46例,良性病灶32例。超声造影在鉴别肿瘤良恶性的特异性为91.7%,准确性92.3%,敏感性为92.8%,显然比常规超声更有效。结论:进行实时灰阶超声造影时应用静脉团注Sono Vue法对肝局灶性病变良恶性的鉴别诊断有帮助。
OBJECTIVE: To discuss the use of Sono Vue for contrast-enhanced ultrasound in the identification of benign and malignant liver tumors compared with conventional ultrasound. Methods: A retrospective analysis was performed on 78 patients with focal focal liver lesions (FLL) detected by conventional ultrasound. According to the characteristics of color and two-dimensional Doppler, after the initial diagnosis of benign and malignant tumors was concluded, And then the ultrasound contrast, analysis of the contrast agent perfusion process, to amend the initial judgment; the last gold standard pathological results, with statistical analysis.Results: Pathological results showed that 78 lesions, 46 cases of malignant lesions, benign lesions 32 The specificity of contrast-enhanced ultrasound in the differential diagnosis of benign and malignant tumors was 91.7%, the accuracy was 92.3% and the sensitivity was 92.8%, which was obviously more effective than conventional ultrasound.Conclusion: Sono Vue method On the differential diagnosis of benign and malignant focal liver lesions helpful.
