摘要
目的在扩大临床应用基础上，考察国产^99Tc^m-双半胱氨酸（Ec）注射液的有效性、安全性和不良反应。方法全国8个省、市的14家医院参加了该次临床多中心试验。分析11批次药盒的328例^99Tc^m-EC肾动态显像结果，并进行药物质量控制指标、图像质量和药物安全性评价。结果11批药盒标记后放化纯均〉90％。各项药物质量控制指标均符合要求。显像质量达到临床要求，肾影显示较好，图像清晰，显像成功率达100％。试验过程中各研究中心患者均无不良事件发生。结论国产^99Tc^m-药盒用作肾动态功能显像剂质量优良、使用安全。
Objective ^99Tc^m-ethylenedieysteine （EC） is a new radiopharmaceutical for renal dynamic imaging produced by Jiangsu Institute of Nuclear Medicine,China. The aim of this phase Ⅳ clinical trial was to evaluate the efficacy and safety of ^99Tc^m-EC in a large number of patients with various renal disorders. Methods Fourteen Chinese hospitals had participated in this multi-center clinical trial. The ^99Tc^m- EC kits from eleven production batches were used. Three hundred and twenty-eight patients were entered into the study. Patients were intravenously injected with ^99Tc^m-EC and a series of dynamic renal imaging was acquired in each patient. The quality of kits and images was analyzed. Possible adverse events were observed and recorded. Results All quality control parameters of the radiopharmaceutical kits were up to the standard requirement. The radiochemical purity of ^99Tc^m-EC in all production batches exceeded 90%. All functioning kidneys were clearly visualized and high-quality renograms were obtained in all 328 patients. No adverse events were recorded during or after the examination process. Conclusion ^99Tc^m-EC is a potentially useful radiopharmaceutical in dynamic renal functional studies.
