目的探讨不同静脉注射方法对99mTc-DTPA肾动态显像弹丸注射质量的影响.方法回顾性分析395例进行99mTc-DTPA肾动态显像检查患者的临床资料,根据注射方法分成:静脉直接注射组(187例)、静脉液路注射组(84例)及静脉留置针注射组(124例).3组采用各自弹丸注射方法进行显像.利用Xeleris工作站在血流灌注显像于腹主动脉勾画感兴趣区(ROI),得到ROI的时间-放射性曲线,以形成1个放射峰为弹丸注射成功,无峰形成为注射失败.统计3组成功及失败例数,利用SPSS17.0软件进行x2检验.结果静脉直接注射组弹丸注射成功174例,成功率93.0％,静脉液路注射组成功46例,成功率54.8％,静脉留置针注射组成功115例,成功率92.7％.静脉直接注射组与静脉留置针注射组成功率高于静脉液路注射组,差异有统计学意义,静脉直接注射组与静脉留置针注射组成功率比较差异无统计学意义.结论静脉留置针注射法弹丸成功率与静脉直接注射法相当,可选择静脉留置针进行注射;静脉液路注射法成功率低于其他2组,应谨慎选择.

Objective To explore the influence of different injection techniques on the quality of bolus in 99mTc-DTPA renal dynamic imaging.Methods 395 patients accepted 99mTc-DTPA renal dynamic imaging were retrospectively analyzed.All patients were divided into three groups according to injection techniques:direct injection group (187 cases),intravenous route injection group (84 cases)and venous indwelling needle injection group (124 cases).The three groups were injected by each technique.Areas of interest (ROI) were drawn on abdominal aorta by Xeleris workstation in blood flow perfusion imaging.The time-radioactivity curves of ROI were got.The patients whose ROI curve formed a peak was successfully injected,and did not formed was unsuccessfully injected.The number of patients in three groups who were successfully or unsuccessfully injected was respectively calculated.The data of three groups was taken Chisquare test by SPSS17.0 software.Results 174 patients of the direct injection group,46 of the intravenous route injection group and 115 of the venous indwelling needle injection group were injected successfully.The successful rate respectively was 93.0％,54.8％ and 92.7％.The successful rate of the direct injection group and venous indwelling needle injection group were higher than intravenous route injection group.The difference had statistical significance.The successful rate of the direct injection group and venous indwelling needle injection group hadn't statistical significance.Conclusions The successful rates of the direct injection group and venous indwelling needle injection group were similar.The venous indwelling needle injection technique can be chosen.The successful rate of the intravenous route injection group was lower than the other two groups.The intravenous route injection technique should be chosen prudently.
