| 摘 要： | 目的探讨不同操作者进行勾划设置感兴趣区对Gates法测定肾小球滤过率的影响。方法对55例患者行肾动态显像,2位勾划者设置感兴趣区并得出肾动态显像测定肾小球滤过率(GFR)。比较2次勾划所得GFR的相关性。结果 2次勾划所得GFR差异无统计学意义(49.94±18.81比49.78±18.48,P>0.05),相关系数为0.961(P<0.01)。结论 Gates法测定肾小球滤过率有较好的重复性,受勾划者影响较小。

| Abstract: | Objective To investigate the influence of different region-of-interest （ ROI ） drawing on the measurement of glomerular filtration rate （GFR） with Gates＇ method. Methods Dynamic renal imaging was performed in 55 patients. GFR was calculated from different ROI drawed by two different observers and was compared by using linear regression analysis. Results No significant difference was observed in GFR obtained from two observers（49. 94±18. 81 vs. 49.78±18.48 ,P 〉0. 05）. The correlation coefficient of GFR from 2 observers was 0. 961 （P 〈0. 01 ）. Conclusion The measurement of GFR in Gates＇method displays good interobserver reproducibility. |
