摘　　要：目的:探讨肾动态显像图像质量常见的影响因素及其质量控制,以期获得优质的肾动态显像图像。方法:选取588例患者的肾动态显像资料进行回顾性分析,对图像质量进行评判,分析肾动态显像图像质量的影响因素。结果:588例肾动态显像图像中,图像质量良好506例(占86%);图像质量较差54例(占9.2%);图像质量差19例(占3.2%);图像质量与患者真实临床资料不符9例(占1.6%)。影响肾动态显像图像质量的主要因素为检查前患者的准备、放射性药物及医护人员的操作技术等。结论:影响肾动态显像图像质量的环节和因素很多,而其中医护人员的操作技术是影响图像质量的最主要因素,需努力提高操作人员静脉穿刺技术。Objective:To explore common influence factors and quality control for imagequality of dynamic renography so as to obtain better dynamic renography.Methods:Aretrospective analysis was applied to analyze the dynamic renography data of588patients,and the image quality was evaluated,and their effect factors were analyzed based on abovedata.Results:In588dynamic renography data,506cases(86%)were good in image quality,and54cases(9.2%)were poorer in image quality,and19cases(3.2%)were worst.Besides,there were9cases(1.6%)were discordance between image quality and real clinical data ofpatients.The main factors that affected the dynamic renography image quality included:the preparation of patientin pre-detection,radiopharmaceuticals and operative technique of paramedic,etc.Conclusion:In those links andeffect factors,the most important one is vein puncture operative technique of paramedic.Therefore,vein puncturetechnique of paramedic should be further enhanced and improved.
