摘　　要：目的:应用螺旋增强CT对肾小球滤过率进行研究,从而对这一种新的肾功能评价方法的可行性作一探讨。方法:应用增强螺旋CT及两点法(两参数)PatlakPlot技术,对三个年龄组:低年龄组25～35岁;中年龄组36～45岁;高年龄组46～60岁各30例的肾小球滤过率进行了测评,所得结果同实验室方法测定的肾小球滤过率结果进行对比。结果:三个年龄组CT肾小球滤过率与内生肌酐清除率均存在明显线性相关。高年龄组:r值为0.83;中年龄组:r值为0.88;低年龄组:r值为0.64。结论:应用螺旋增强CT可以对无相关性肾疾病的肾小球滤过率做一大致的评估,其在不同的年龄段均可应用,可做为肾功能评价方面的一种新途径。Objective： To study glomerular filtration rate by using enhanced spiral computed tomography in order to explore its feasibility in assessing kidney function. Methods： Glomerular filtration rate was measured and assessed in three age groups： 25-35 year old group; 36-45 year old group; 46-60 year old group, 30 cases in each group, according to two-compartmental Patlak Plot technique and using enhanced spiral computed tomography. Correlation of the result by comparing the data of experimentation was obtained. Results： CT glomerular filtration rates and Ccrs of three age groups have obvious correlation. R-value of old age group is 0.83; r-value of middle age group is 0.88; r-value of young age group is 0.64. Condusion： Glomerular filtration of no-related kidney illness function measured and assessed using enhanced spiral computed tomography is a new way to assess kidney function, that can apply in different age group, the developmental trend is broad.
