目的：对比研究 PET ／CT 检查时18F‐脱氧葡萄糖（18F‐FDG）显像剂3种不同静脉注射法的穿刺成功率、药物注射残留量及工作人员射线接触时间的差异及意义。方法将240例 PET ／CT 检查患者分为 A 、B 、C 3组，每组各80例，分别用传统直接注射法、留置针注射法和头皮静脉针连接注射器（留置气泡）注射法进行注射，比较各组穿刺给药成功率、药物残留量、工作人员接触放射性药物时间，对相关数据进行统计分析。结果头皮静脉针连接注射器（留置气泡）注射法和留置针注射法比传统直接注射法穿刺成功率高、工作人员接触放射性药物时间明显减少，差异有统计学意义（P＜0．01）；头皮静脉针连接注射器（留置气泡）注射法比留置针注射法和传统直接注射法注射器内放射性药物残留量显著降低，差异有统计学意义（P＜0．01）。结论头皮静脉针连接注射器（留置气泡）注射法显著提高了穿刺成功率，减少了放射性药物残留，同时减少了工作人员的射线接触时间，该方法在核素注射时具有优势。

Objective To comparatively study the differences of 18F‐FDG imaging agent by three kinds of different intravenous injection method for conducting PET / CT examination in aspects of the puncture success rate ,residual amount of drug injection and staff ray exposure time and their significance .Methods 240 patients with PET /CT examination were randomly divided into the group A ,B and C ,80 cases in each group .The drug injection adopted the traditional direct injection ,indwelling catheter injection and scalp venous needle connecting syringe(indwelling bubbles) .The puncture success rate ,drug residues and staff contacting radio‐pharmaceuticals time were compared among 3 groups .The obtained relevant data were statistically analyzed .Results The puncture success rate in the scalp venous needle connecting syringe (indwelling bubbles) and the indwelling catheter injection was higher than that in the traditional direct injection and the staff contacting radiopharmaceuticals time was significantly decreased ,the differ‐ences among them were statistically significant(P< 0 .01) ;the radioactive drugs residue in the scalp venous needle connecting syr‐inge was significantly decreased than that in other two kinds of injection method ,the difference was statistically significant (P <0 .01) .Conclusion The injection method of scalp intravenous needle connecting syringe (indwelling bubbles) significantly increases the puncture success rate ,reduces the radioactive drug residue ,at the same time decreases the staff radiation exposure time ,this method has the advantage in the radionuclide injection .
