静脉血管选择对^(99m)Tc-DTPA肾动态显像弹丸注射质量的影响

Effect of veins to the quality of bolus injection in ^(99m)Tc-DTPA renal dynamic imaging

目的:探讨不同部位静脉血管对99mTc-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99mTc-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.
