摘　　要：目的:初步探讨声脉冲辐射力弹性成像技术在门静脉栓子良恶性鉴别中的诊断价值。材料与方法:采用声脉冲辐射力弹性成像技术VTQ技术定量检测40例门静脉栓子(包括27例门静脉癌栓,2例混合性栓子,11例门静脉血栓)的SWV值,应用VTI弹性图显示癌栓亮度,综合评估ARFI技术的诊断效能。结果:声脉冲辐射力弹性成像技术诊断门静脉癌栓的敏感性和特异性分别为86.2%和81.8%,结论:声脉冲辐射力弹性成像技术在鉴别出门静脉栓子的良恶性方面具有非常重要的临床价值。Purpose： To evaluate the diagnostic value of acoustic radiation force impulse（ ARFI） images in differential diagnosis of portal vein thrombosis. Materials and Methods： virtual touch tissue quantification（ VTQ） of acoustic radiation force impulse（ ARFI） imaging technique was performed on 40 patients with portal vein thrombosis,included 27 portal vein tumor thrombosis,2 portal vein mixed thrombosis and 11 portal vein benign thrombosis,expressed as shear wave velocity（ SWV）. The brightness of tumor was detected for the indication of stiffness. The results of VTQ and VTI were performed to assess the therapeutic response. Results： The sensitivity and specificity in diagnosis of portal vein thrombosis with ARFI were86. 2%,81. 8%. Conclusion： ARFI elastography play an important role in differential diagnosis between portal vein tumor thrombosis and benign thrombosis.
