摘要
目的探讨通过左、右肘注射对比剂对颈动脉CT造影(CTA)成像图像质量的影响。方法回顾性分析2019-09至2021-06在武警北京总队医院医学影像科行头颈部CTA检查的100例患者,其中50例经右臂肘正中静脉注射对比剂的为右臂组,50例经左臂肘正中静脉注射对比剂的为左臂组;对比两组患者两侧颈动脉CT值及静脉显影优良率。结果右臂组及左臂组的左颈总动脉CT值分别为(335.25±20.67)Hu、(315.78±20.67)Hu,右颈总动脉CT值分别为(330.28±18.45)Hu、(313.56±19.45)Hu,差异无统计学意义(P>0.05);右臂组静脉显影优良率为86.00%,高于左臂组的63.00%,差异有统计学意义(P<0.05)。结论颈动脉CT血管造影采用右臂静脉注射对比剂,可减少上腔静脉、头臂静脉、锁骨下静脉伪影及对比剂反流。
Objective To investigate the effect of contrast agent injection on the image quality of carotid artery CTA imaging through left and right elbow.Methods A retrospective analysis was performed on 100 patients who underwent head and neck CTA examination in the medical imaging department of Beijing Provincial Corps Hospital of Chinese People’s Armed Police Force from September 2019 to June 2021.Fifty patients who received contrast agent through the right elbow vein were in the right arm group,and the other fifty patients were in the left arm group.The CT values of bilateral carotid arteries and the excellent and good rate of venous development were compared between the two groups.Results The CT values of left common carotid artery in right arm group and left arm group were(335.25±20.67)Hu and(315.78±20.67)Hu,respectively,the CT values of right common carotid artery were(330.28±18.45)Hu and(313.56±19.45)Hu,respectively,and the difference was not statistically significant.The excellent and good rate of vein imaging in right arm group was 86.00%,which was higher than 63.00%in left arm group,and the difference was statistically significant(P<0.05).Conclusions Carotid CT angiography with right arm vein injection of contrast agent can reduce artifacts of superior vena cava,brachiocephalic vein and subclavian vein,and provide a reliable foundation for clinical diagnosis and treatment.
