摘要
作者就经手术及／或病理证实的≤３ｃｍ的肝内占位病变５６例共７１个病灶进行了彩色多普勒（ＣＤ）和脉冲多普勒（ＰＤ）的联合研究，结果表明肝内占位病变在ＣＤ上可显示短线状彩色血液，ＰＤ可测及动脉频谱，ＣＤ和ＰＤ相结合，则在小肝癌中有８６．９６％可检测到动脉频谱，而肝血管瘤和肝良性病变中仅分别为３７％和３３％，明显低于小肝癌组。如以肝内小病灶内出现彩色血流并测及动脉频谱和阻力指数大于５０％作为诊断小肝癌的判断指标，则多普勒超声诊断小肝癌的特异性（９６％）、准确性（９０．１４％）均显著高于单纯的二维超声（分别为５６％和６７．６％）。因此，ＣＤ结合ＰＤ可作为超声诊断小肝癌的新手段。
AbstractThe combined studies by using color Doppler(CD)and pulsed Doppler(PD)technique in 56 pa-tients with 71 solid hepatic lesions smaller than 3 cm indiameter were carried out.The detecting rates of arte-rial signals in small hepatocellular carcinomas(sHCC)group, hepatic cavernous hemangiomas(HCH)groupand others group were 86.9%,37%and 33%respec-tively.Whereas,the average value of resistance index(RI)in sHCC group was very higher than that in othergroups,By using combined CD and PD space- taking le-sions of the liver are tentatively diagnosed as sHCC un-der conditions of color flow,arterial signals,and a RIof more than 50%. The specificity(96%)and accura-cy(90%)of the diagnosis superior to the conventionalUS(P<0.005).
