全自动远程核素分药仪的临床应用

目的 探明全自动远程核素分药仪在临床上的实用性,以减少对操作人员的辐射损伤。方法 利用该设备分发不同体积的多管样本,以检测分药仪取样精度和核素活度,并用该仪器分药和手工分药分组治疗甲亢患者,进行对比研究,观察其治疗效果。结果 该分药仪取样的绝对误差都在0.1 ml以内,且分药过程对药物的放射性活度没有影响,仪器分药组和手工分药组治疗甲亢患者的效果没有明显的差别。结论 全自动核素分药仪分药准确、可靠,减少了对操作人员的辐射损伤。

Clinical application of automatic instrument for distribution of radio nuclide through remote operation

Objective In this study,we explored the potential clinical application of the instrument for automatic distribution of isotopes in order to reduce the injuries to operators by radiation.Methods The accuracy of samples and activities of isotopes were determined by acquisition of the samples through the instrument distributing multiple samples at different volumes.In addition,the therapeutical effects on the patients with thyroidism were compared between those who were treated by the isotope distributed via the instrument(IDI group)and those who were treated by the isotope distributed manually(IDM group).Results Acquisition errors by the instrument were under 0.1ml and the isotope distribution didn't affect the activity of radiation.Moreover,no significant difference was observed between the IDI group and the IDM group.Conclusion Isotope distribution by the instrument is accurate and reliable.And by this proceeding,radiation injuries to operators are decreased.
