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 image quality of dynamic renography so as to obtain better dynamic renography.Methods: A retrospective analysis was applied to analyze the dynamic renography data of 588 patients, and the image quality was evaluated, and their effect factors were analyzed based on above data.Results: In 588 dynamic renography data, 506 cases (86%) were good in image quality, and 54 cases (9.2%) were poorer in image quality, and 19 cases (3.2%) were worst. Besides, there were 9 cases (1.6%) were discordance between image quality and real clinical data of patients. The main factors that affected the dynamic renography image quality included: the preparation of patient in pre-detection, radiopharmaceuticals and operative technique of paramedic, etc.Conclusion: In those links and effect factors, the most important one is vein puncture operative technique of paramedic . Therefore, vein puncture technique of paramedic should be further enhanced and improved.
