摘要目的探讨超声结合声触诊组织量化(VTQ)技术在肝包虫囊肿退行性变中的应用研究。方法对经手术病理证实的27例28个退行性变的肝包虫囊肿在经超声检查的同时应用VTQ技术检测包虫囊内容物的剪切波速度(Vs)，并结合临床病理改变资料进行对比分析。结果囊内容物为胶冻状组囊内呈密集不均匀的点片状及带状回声，无双层壁结构；囊内容物为实性变组囊内呈不均质的实性回声，有不规则的斑片状及条状强回声，囊壁粗糙伴强回声。退行性变包虫囊肿实性变组Vs值高于胶冻状组(P<0.001)；胆瘘组Vs值高于无胆瘘组(P<0.01)；钙化组Vs值高于无钙化组(P=0.001)。结论超声结合VTQ技术在判断肝包虫囊肿病理性退行性变方面具有重要价值。

Abstract ObjectiveTo evaluate the application of hepatic hydatid cyst degeneration in ultrasound and virtual touch tissue quantification(VTQ ).Methods 27 cases with 28 hepatic hydatid cysts degeneration confirmed by the operation and pathology underwent sonography and measured the shear wave velocity(Vs)values of the cyst content.Results The ultrasonography of the jelly in the cyst showed the dense spotted and stripped echoes without double cystic wall.The ultrasonography of the solid in the cyst showed inhomogeneous solid with the high echoes of the irregular flakes and strips，the wall of the cysts was rough and had the high echoes.The Vs values of the solid in the cyst were higher than the jelly in the cyst(P<0.001).The Vs values of the biliary fistula group were higher than the non biliary fistula group(P<0.01).The Vs values of the calcification group were higher than the non calcification group(P=0.001).Conclusion Ultrasound and VTQ have important value in judging degree of hepatic hydatid cyst degeneration.

肝包虫囊肿退行性变是其自然生长过程，对肝包虫囊肿退行性变程度判断方法的研究报道有限且具有局限性[1，2]。本研究将超声结合声触诊组织量化(Virtual touch tissue quantification， VTQ )技术与临床病理改变相结合，对肝包虫囊肿退行性变程度判断做相关分析研究。

1资料与方法

1.1临床资料

研究对象为2013年1月～2015年1月在青海省人民医院住院诊治，并经手术病理证实为肝包虫囊肿退行性变患者27例〔男15例，女12例，年龄23～70岁，平均(44±13.78)岁〕，共28个囊肿(胶冻状囊肿13个，实性变囊肿15个)。

1.2方法

采用Siemens Acuson S-2000彩色超声仪(配有VTQ技术软件)，将仪器设置为Abdmon条件，采用4C-1凸阵探头[频率(2～4)MHZ]。……
