目的：探讨不同部位静脉血管对99m Tc-DTPA肾动态显像弹丸注射质量的影响。方法：选择2012年1~4月、2012年5~8月、2012年9~12月我院行肾动态显像时分别在手背静脉、腕部静脉、肘部静脉注射显影剂，静脉穿刺成功，注射部位无显像剂漏出的380例患者。比较手背部组(129例)、腕部组(134例)、肘部组(117例)弹丸式注射的成功率，探讨血流灌注图质量。结果：3组弹丸式注射成功率比较，差异无统计学意义(P>0.05)。成功者血流灌注图可见腹主动脉区放射性浓聚影，腹主动脉ROI时间-放射性曲线高尖放射峰；失败者血流灌注图像腹主动脉区未见放射性浓聚影，腹主动脉ROI时间-放射性曲线未形成放射峰，曲线先升高后呈平台样缓慢上升。结论：腕部及手背部静脉可进行99m Tc-DTPA肾动态显像弹丸注射，当肘部静脉适合穿刺时，仍以肘部静脉注射为首选。

To explore the effect of veins selection to the quality of bolus injection in 99m Tc-DTPA renal dynamic imaging. Methods:Cases of 380 patients accepted 99m Tc-DTPA renal dynamic imaging,were the vein puncture success,no imaging agent leaking at the injection site were prospectively an-alysed. All patients were divided into opisthenar group (129 cases),wrist group(134 cases),elbow group (117 cases)respectively,according to the time. The success rates of bolus injection in 3 groups were compared,the bolus injection quality of 3 groups were analysed. Results:There was no statistical signifi-cance among the success rate of bolus injection in three groups (P>0. 05). Aorta perfusion image area of winners was radioactive thick,ROI-radioactive curve was emission peak time. Aorta perfusion image area of losers was no radioactive thick,ROI-radioactive curve was curve increases after the first sample platform slowly rising. Conclusion:Wrist and hand back vein can be bolus injection in 99m Tc-DTPA renal dynamic imaging,when the elbow vein could be chosen,elbow vein is first selection.
