目的:分析超声造影(Contrast-enhanced Ultrasonography CEUS)和增强CT在小肾癌中的表现特征,探讨超声造影在诊断小肾癌中的应用价值与临床意义.方法:选取2011年4月-2014年12月在我院住院经手术病理证实为小肾癌的患者62例(62个病灶),分析超声造影和增强CT的表现.比较两种方法对小肾癌的灌注特征、诊断率、假包膜及病灶坏死区显示率.结果:本组62个肿块经手术后病理证实肾透明细胞癌56例,肾嫌色细胞癌3例,乳头状肾细胞癌2例,嗜酸细胞腺瘤1例(潜在恶性).小肾癌在超声造影和增强CT中的灌注特征表现分别为"快进慢退"者80.12%和"快进快退"者83.49%.小肾癌在超声造影和增强CT中的诊断率分别为86.35%和87.27%.小肾癌在超声造影和增强CT假包膜显示率分别为68.45%和37.65%.小肾癌在超声造影和增强CT病灶坏死区显示率分别为62.15%和64.30%.超声造影和增强CT对小肾癌诊断率及病灶坏死区显示率均无统计学差异(P>0.05),对假包膜显示率有统计学差异(P<0.05),小肾癌多为富血供病灶,呈"快进慢退、弥漫性高增强"是其超声造影特征表现.结论:超声造影在诊断小肾癌中具有一定的临床应用价值,可作为诊断的一种重要方法,与增强CT起到相辅相成的作用,减少漏诊.
