【摘要】 目的 :应用二维及彩色多普勒超声诊断胆管细胞型肝癌 ( CC)。方法 :分析 17例经病理证实的 CC的超声图像特点 ,其中男 8例 ,女 9例 ,平均年龄 5 6岁。结果 :1CC多表现为肝内单发实性肿块 ,形状不规则 ,边界不清楚 ;2 CC占位效应不明显 ,位于肝表面可见“脐凹”,并可包绕或跨越 Glisson系统生长 ;3内部多为均匀低回声 ,边缘回声略强 ;4CDFI检查显示肿块内血流信号稀少或见不到。本组病例阳性预期值 88% ,诊断准确率 82 %。结论 :超声诊断 CC有较高的应用价值 ,其特异性优于 CT检查更多还原

【Abstract】 Objective: To diagnose cholangiocellular carcinoma(CC)with twodimensional and color Doppler ultrasonographyMethods:Seventeen confirmed CC cases were ultrasonographically analysedThey are 8 male,9 female with mean age 56 yearsResults:CC commonly presents as intrahepatic solitary solid mass with irregular shape and unclear marginThe mass effect of the tumor was not obvious,sometimes presented as umbilicus concave,if located at or grew around or over Glisson systemThe tumor inner echo was evenly weak,but heavy echo in the outer areaCDFI showed sparce or no blood flow signal within the tumorsThe positive expective value is 80% and diagnostic accuracy rate is 82%.Conclusion:Ultrasound possesses higher clinical value in diagnosing CC,its specificity is better than CT更多还原
