摘要
目的 :评价阻力指数(RI)和搏动指数(PI)在弥漫性脾肿大病因鉴别诊断中的应用价值。材料与方法 :对象为各种常见的弥漫性脾肿大患者81例和正常人32例 ,使用彩色多普勒血流显像(CDFI)及彩色多普勒能量图(CDE)显示脾动脉及其分支 ,测量RI和PI。结果 :肝硬化组脾动脉及其分支的RI和PI较正常组和其它疾病组增高(P<0 05)。结论 :在临床上脾动脉及其分支的RI和PI可帮助区别肝硬化脾大和其它疾病导致的脾肿大。
Objective:To evaluate the ability of Doppler ultrasonography in the differential diagnosis of splenomegaly with the application of both color Doppler flow imaging(CDFI) and color Doppler energy (CDE).Materials and Methods:The splenic impedance indices were evaluated in 32 controls and 81 patients with splenomegaly of various causes,which divided into seven groups.CDFI allowed the identification of the splenic vessels at the hilus,and CDE allowed the identification of the branches of splenic arteria.Results:The splenic impedance indices of cirrhosis were higher compared with controls and other groups(P<0 05). Conclusions:CDE provided more complete visualization of the splenic vessel tree,so Doppler ultrasonography assessment of splenic hemodynamics can be all sidedly.
