超声造影对肝内低回声占位病变的鉴别诊断

Contrast-enhanced ultrasound in the differential diagnosis of low echo-level focal liver lesions

目的:探讨超声造影对肝内低回声占位病变诊断的临床价值。方法:对常规超声不能明确诊断的肝内低回声占位病变患者55例进行超声造影检查,并与病理结果对照。结果:55例病灶肝内低回声占位病变中,超声造影定性诊断51例(92.7%),其中良性病变造影主要表现为"慢进慢出"或"同进同出",恶性病变造影主要表现为"快进快出"。结论:超声造影可有效动态地评价肝肿瘤的血管化程度,提高了超声对肝局灶性占位病变诊断的准确性。

Objective：To explore the clinical value of contrast-enhanced ultrasonography in the diagnosis of low echo-level focal liver lesions.Methods： Fifty five patients of low echo-level focal liver lesions not confirmed by common ultrasound were examined by contrast-enhanced ultrasonography and compared to pathology resalts.Results： In 55 low echo-level focal liver lesions,the qualitative diagnosis accuracy of contrast-enhanced ultrasonography was 92.7%（51/55）,benign tumor of contrast-enhanced ultrasonography shoed mainly ＂slow enhancement and expurgation＂ or ＂enhanced simultaneously＂,malignant tumor of showed mainly ＂swift enhancement in the arterial phase and swift expurgation in the portal phase＂.Conclusion： Contrast-enhanced ultrasonography could evaluate the vascularization of liver tumors effectively and improve the accuracy of ultrasound for focal liver lesions
