评估SPECT测定不同年龄段健康人肾小球滤过率的准确性
Estimate the accuracy of SPECT determination glomerular filtration rate in different age healthy people
摘要
Abstract
Objective: To estimate the accuracy of SPECT determination glomerular filtration rate in different age healthy groups. Methods: Totally 232 Beijing community health residents were selected as the research subjects. Two-sample method and 99Tcm-DTPA dynamic renal imaging were used for determination of GFR (GFRdt and GFRGates, respectively). GFRdt as the reference standard, compare the accuracy of six different age groups GFRGates which get by SPECT Results: ①There were significant differences between GFRdt and GFRcates on six different age groups. ②GFRGates from Six different age groups were significantly lower than those of GFRdt. The difference in the group of 30-39years between GFRdt and GFRGates is maximum, the mean difference is (-34.26±20.79) ml/(min·1.73m)2. The difference in the group of >70years between GFRdt and GFRGates is minimum, the mean difference is (-23.62± 18.60) ml/(min·1.73m)2. ③GFRdt and GFRgates derived from the group 30-39years had the worst correlation (r=0.42). GFRdt and GFRGates derived from the group >70years had the best correlation (r=0.81). Conclusion: The accuracy of GFR which got by SPECT is poor in 20-49years health group, it is better in >50 years health group, while it is the best in >70 years health group.关键词
