摘要
目的:探讨对比剂团注跟踪造影技术(Bolus Chasing)在下肢动脉造影中的临床应用价值及其质量控制。方法:采用对比剂团注跟踪技术对33例患者行下肢动脉造影,并与传统DSA分段造影法(12例)进行对比,分别比较二者的患者X线吸收剂量、对比剂用量、造影完成时间,并对团注跟踪造影图像质量进行分级评价。结果:对比剂团注跟踪技术和传统DSA分段造影法完成单侧下肢动脉造影患者X线吸收剂量分别为(11.00±1.37)mGy和(22.33±2.23)mGy,对比剂用量分别为(19.27±1.92)ml和(28.50±2.28)ml,造影完成时间分别为(4.38±0.49)min和(12.37±0.84)min,差异具有显著性意义(P<0.05)。结论:采用对比剂团注跟踪技术进行下肢动脉造影较传统分段造影技术具有使用对比剂少、检查时间短、图像直观等优点,且能一次性准确显示全下肢血管的解剖情况,值得临床进一步推广应用。
Objective：To study the value of bolus chasing technology in limb artery angiography and its quality control. Methods：33 cases underwent lower limb artery angiography by using bolus chasing technology,and 12 eases by using traditional DSA segmentation method. The radiation dose, the dosage of contrast agents, completion time and image quality were compared between the two groups. Results.. The radiation dose were （11.00± 1.37）mGy （bolus chasing group） and （22.33± 2.23）mGy （traditional DSA segmentation method）, respectively. The dosage of contrast agents were （19.27±1.92）ml and （28.50±2.28）ml,respectively. And the completion time were （4.38±0.49）min and （12.37±0.84）rain. Conclasion：Bolus chasing technology is a good method in limb artery angiography with a low dose of radiation,a short time of examination and good quality of imaging.
