| 摘 要： | 目的探讨彩色多普勒超声在诊断肾血管平滑肌脂肪瘤(RAL)中的应用价值.材料和方法应用二维超声、彩色多普勒血流图(CDFI)、彩色能量多普勒血流图(PDI),结合脉冲多普勒频谱对25例肾血管平滑肌脂肪瘤进行研究.结果CDFI对RAL内血流显示率36%,PDI对RAL血流显示率92%.RAL血流呈低速高阻型.阻力指数(RI)＞0.6(91.3%),动脉峰速55cm/s(86.96%).结论CDFI、PDI对RAL的诊断有重要价值.

| Abstract: | Purpose: To evaluate color Doppler ultrasound in the diagnosis of renal angiomyolipoma. Materials and Methods: 25 renal angiomyolipoma (RAL) were studied by two dimensional ultrasonography, color Doppler flow imaging (CDFI), power Doppler imaging (PDI) and pulsed wave Doppler (Pw). Results: CDFI was less sensitive in revealing angiomyolipoma blood flow (36%) than PDI (92%). CDFI showed a low velocity and high resistance blood flow in renal angiomyolipoma with a resistance index (RI) more than 0.6 (91.3%) and a maximum blood flow velocity less than 55cm/s (86.96%). Conclusion: CDFI and PDI were useful in the diagnosis of renal angiomyolipoma. |
