摘　　要：目的　探讨二维超声图像及三维超声血流图和能量图对肾癌和肾柱肥大的鉴别诊断价值。方法　使用麦迪逊公司VOLUSON 5 3 0D ,彩色多普勒超声及三维成像系统 ,凸阵探头频率为 3 .0～ 5 .0MHz。对经临床随访证实的 2 0例患者进行超声检查 ,其中肾柱肥大 12例 ,肾癌 8例 ,肾癌患者中 7例经手术证实。结果　肾柱肥大的肾血管为逐级分布的树枝状结构 ,超声多普勒血流指数均为正常值范围 ,而肾肿瘤内血管走行杂乱 ,依肿物大小及形态构成异常的网状结构。肿瘤内动脉流速高于正常平均值。结论　三维超声血流图及能量图能明确显示肾癌和肾柱肥大的血流情况 ,为鉴别诊断提供了可靠依据或信息 ,并弥补了二维超声及多普勒超声对少血供肾肿瘤不能有效显示血流的不足。Objective To research the value of differential diagnosis between renal columnar hypertrophy and renal carcinoma by two-dimensional (2D) sonography and 3-dimensional(3D) sonography with color Doppler flow imaging and color Doppler energy.Methods Twelve renal columnar hypertrophy patients and eight renal carcinoma patients were investigated by VOLUSON-530D,and seven patients in renal tumor were confirmed by operation.Results The flow of renal columnar hypertrophy distribution was branching,both RI and PI were in normal range.Blood vessel of solid lesion of kidney lost the normal distribution and formed a reticular structure according to the size and shape of the mass. Both Vmax and Vmin of arterial flow in the tumors were higher than those in the normal.Conclusion The CDFI and CDE of three-dimensional sonography can demonstrate the flow situation of renal columnar hypertrophy and solid lesion of kidney clearly,which can provide a reliable method for the differential diagnosis.
