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）Patlak Plot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。
Abstract
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. Conclusion: 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.
