超声造影对肝局灶性病变病灶类型诊断的应用价值

Evaluation of the usefulness of contrast-enhanced ultrasound for differential diagnosis of focal liver lesions

目的探讨超声造影对肝局灶性病变病灶类型判断的能力。方法比较研究常规超声及低机械指数超声造影对238例298个肝局灶性病变鉴别诊断的效能。结果298个肝局灶性病变常规超声正确诊断病变类型159个(53.4%),超声造影正确诊断病变类型279个(93.6%),两者比较有统计学差异(P<0.01)。结论超声造影提高了超声正确诊断肝局灶性病变病灶类型的能力。

Objective To investigate differential diagnosis for focal liver lesions using contrast-enhanced ultrasound.Methods Two hundred and ninety-eight lesions in 238 patients with focal liver lesions were scanned by baseline US and low mechanical index contrast gray-scale imaging.Results Contrast-enhanced ultrasound improved correctly diagnosing rate of hepatic lesion types was from 53.4%（159/298）to 93.6%（279/298）,compared with baseline sonography.Conclusion Contrast-enhanced sonography improved differentiation ability for focal liver lesion.
