Abstract：Objective: To analyze the main influencing factors and variation tendency of renal dynamic+GFR examination quality, so as to take appropriate measures to ensure its quality. Methods: The reasons for reexamination of 596 patients (control group) in 9 653 cases of renal dynamic+GFR examination were analyzed retrospectively, and the main influencing factors and improvement measures were found, and the reasons for reexamination of 374 patients(observation group) were analyzed again in 12 960 cases. The total reexamination rate, the main influencing factors and the changes of the age distribution of the subjects were observed. SPSS 12.0 statistical analysis software was used for data processing, and χ2 test was used for comparison among groups, and the test level was α=0.05. Results: The reexamination rates of the control group and the observation group were 6.17%(596/9 653) and 2.89%(374/12 960) respectively, and the differences were statistically significant between the two groups(χ2=145.72, P<0.05). Main influencing factors: patient factors, injection technical factors, comprehensive assessment inconsistent with clinical or other diagnosis factors, the differences were statistically significant(χ2=6.56, 21.43, 8.65, P<0.05). Secondary influencing factors: imaging agent, acquisition and processing, equipment factors, there was no significant difference(χ2=0.004, 0.05, 0.46, P>0.05). Age distribution changes: the number of infants and children increased, the differences were statistically significant between the two groups（χ2=51.10, 202.25, P<0.05）. Conclusion: Renal dynamic+GFR examination has high sensitivity and complicated influencing factors, it is important to analyze the main influencing factors and dynamic changes to ensure the quality of renal dynamic imaging and the accuracy of GFR.
