造影增强能量图对肾灌注形态学及半定量实验研究
The morphological and semi quantitative study of contrast enhanced color Doppler energy in renal perfusion
【摘要】 目的 探讨造影增强肾能量图对缺血性肾灌注形态学的评价价值及利用时间 -强度曲线半定量分析肾灌注功能的应用价值。方法 对 5只实验兔递进性钳夹肾动脉主干 ,对每一钳夹级别均进行造影实验 ,采集实验动态图像 ,分析图像形态特征 ,并依据时间序列对不同部位行时间 -强度曲线半定量分析。结果 造影增强肾能量图可敏感反映缺血状态下皮质外层血流再灌注分配的规律。肾是进行时间 -强度曲线半定量分析的良好脏器 ,时间 -强度曲线的相关参数可有效反映肾血流灌注量的变化。结论 造影增强肾能量图是评价肾组织灌注功能的良好手段
【Abstract】 Objective To evaluate the application value of the contrast enhanced color Doppler energy (CDE) in renal perfuison.Methods The renal arteries of 5 rabbits were progressively stenosed at three level. The morphology characterizes and time intensity curve were studied at every stenosis level after contrast injection as bolus through peripheral vein.Results The contrast enhanced absence of the cortex outer layer was clearly displayed by the contrast enhanced CDE. The contrast enhanced absence represents the reassignment of the re perfusion renal blood under the ischemia condition. The kidney is the good organ in time intensity curve study and the parameters of the curve can effectively describe the renal perfusion.Conclusions Contrast enhanced CDE is good way to valuate the renal perfusion function.
