Abstract: Objective:To analyze the difference of glomerular filtration rate (GFR) among image processing of the renal dynamic imaging through various methods.Methods: The renal dynamic imaging was processed through various methods, and using the image post-processing software. Using SPSS statistic system to analyze the data.Results: The methods of image processing had impacts on GFR. (1)The difference of GFR data obtained from images which were processed by different operators were not statistically significant. (2) The difference of GFR data obtained from images which image processing repeatedly by the same operator were not statistically significant. (3)GFR data measured based on background detecting regions of interest (ROI) (manually defined or auto-defined ROI) placed in different positions of kidney image had statistical significant. (4) The difference of GFR data were measured by manually defined and auto-defined background ROI had statistical significant.Conclusion: Choosing the proper image processing way, combining clinical appearance and detection, and gaining real data help to ensure the accuracy of imaging diagnostic reports.
