摘　　要：目的探讨超声造影在经皮肝占位性病变穿刺活检中的应用价值。方法对196例超声诊断不明的肝占位性病变随机分为两组,其中97例采用超声引导下的穿刺活检(US组),99例行超声造影后进行超声引导下穿刺活检(CEUS组)。标本行组织学检查,取材量满足病理诊断为取材成功,分析两组一次取材成功率和诊断准确率。结果 CEUS组一次取材成功率为98.0%(97/99),诊断准确率为96.0%(95/99);US组分别为91.8%(89/97)和87.6%(85/97)。CEUS组在取材成功率和诊断准确率上均显著高于US组。此外,US组68例恶性病灶中,2例病灶活检阴性,在超声造影引导下再次活检,均被确认恶性。结论超声造影可准确判断肝占位病变坏死、液化区,初步判断病变的良、恶性,引导准确进行定位取材,提高穿刺活检取材满意率及诊断准确率,在肝占位病变穿刺活检中有重要的临床价值。Objective To assess the clinical value of contrast-enhanced uhrasonography in percutaneous liver lesion biopsy guided by ultrasound. Methods One hundred and ninety-six cases underwent ultrasound（US）guided biopsy, among which 99 cases underwent contrast enhanced ultrasound（CEUS）and then biopsy. The biopsy achievement ratio and accurate diagnosis ratio were compared between the two groups. Results The biopsy achievement ratio and accurate diagnosis ratio in CEUS group were 98.0% （97/99）and 96.0% （95/99）, respectively. The biopsy achievement ratio and accurate diagnosis ratio in US group were 91.8%（89/97）and 87.6% （85/97）, respectively. These two ratios were significantly high in CEUS group. Besides, 2 cases in the US group were diagnosed as benign lesions after US-guided biopsy,and were further demonstrated to be malignant after CEUS guided biopsy. Conclusions CEUS could judge the necrotic area of the lesions accurately and the precise location of the lesion. It could improve the biopsy achievement ratio and accurate diagnosis ratio and has great value in the biopsy of local liver lesions.
