能量多普勒显像与彩色多普勒显像诊断13 例肾动脉狭窄意义的探讨

目的 研究能量多普勒显像(PDI) 在中型动脉的显示效果,探讨超声无创性诊断肾动脉狭窄的可能性。方法 使用彩色多普勒血流显像(CDFI) 、能量多普勒显像及脉冲多普勒频谱分析(PWD) 对经血管造影证实的13 例肾动脉狭窄病人进行研究。结果 PDI 能够更好地反映狭窄血管的真实形态,明显增加肾动脉的显示长度和血流的稳定性,减少检查时间。结论 结合使用PWD 及其他超声新技术,PDI 可以很好的用来筛选和诊断肾动脉狭窄。

The Different Manifestation of CDFI and PDI in 13 Patients with Renal Artery Stenosis

Objective To probe into the feasibility in diagnose of renal artery stenosis with simple harmless methods.Methods 13 patients with renal artery stenosis were assess using color Doppler flow imaging (CDFI) and power Dopplerimaging(PDI) and pulsed wave Doppler ( PWD) . Results PDI provides better morphologic feature , better renal arterylength and better flow stability ,as well as a shroter exam time. Conclusion PDI could be used to screen renal artery stenosis from hypertension patients with PWD and a few new techniques.
