摘　　要：目的:观察低剂量对比剂在多排CT头颈部血管造影检查诊断头颈部血管病变中的应用效果。方法:回顾性分析2021年6月至2023年6月于该院行多排CT头颈部血管造影的118例头颈部动脉血管病变患者的临床资料,按造影对比剂量不同将其分为观察组(注射50 mL碘海醇注射液)66例与对照组(注射70 mL碘海醇注射液)52例。两组均给予CT造影检查,比较两组头颈部血管成像对比剂显影CT值、头颈部血管成像对比剂静脉残留显影CT值、图像质量评分,以及造影不良反应发生率。结果:观察组主动脉弓、颈总动脉、颈内动脉、大脑中动脉、椎动脉、基底动脉等对比剂显影CT值均低于对照组,差异有统计学意义(P<0.05);观察组颈内静脉、头臂静脉、上腔静脉、锁骨下静脉等对比剂残留显影CT值均低于对照组,差异有统计学意义(P<0.05);两组图像质量评分比较,差异无统计学意义(P>0.05);观察组造影不良反应发生率为4.55%(3/66),低于对照组的21.15%(11/52),差异有统计学意义(P<0.05)。结论:低剂量对比剂在多排CT头颈部血管造影检查诊断头颈部血管病变的图像质量与常规剂量对比剂无明显差异,且可减少对比剂残留、降低不良反应发生率。Objective:To observe application effect of low-dose contrast agent in diagnosis of head and neck vascular lesions by multislice CT angiography.Methods:The clinical data of 118 patients with head and neck arterial lesions who underwent multi-slice CT angiography in this hospital from June 2021 to June 2023 were retrospectively analyzed.According to different contrast doses,they were divided into observation group(injection of 50 mL Iohexol injection,66 cases)and control group(injection of 70 mL Iohexol injection,52 cases).Both groups were given CT angiography.The CT value of contrast agent in head and neck angiography,the CT value of residual contrast agent in vein in head and neck angiography,the image quality score,and the incidence of adverse reactions of angiography were compared between the two groups.Results:The CT value of aortic arch,common carotid artery,internal carotid artery,middle cerebral artery,vertebral artery and basilar artery in the observation group were lower than those in the control group,and the differences were statistically significant(P<0.05).The CT value of residual contrast agent in internal jugular vein,brachiocephalic vein,superior vena cava and subclavian vein in the observation group were lower than those in the control group,and the differences were statistically significant(P<0.05).There was no significant difference in the image quality score between the two groups(P>0.05).The incidence of adverse reactions in the observation group was 4.55%(3/66),which was lower than 21.15%(11/52)in the control group,and the difference was statistically significant(P<0.05).Conclusions:The is no significant difference in image quality of low-dose contrast agent in the diagnosis of head and neck vascular lesions by multi-slice CT head and neck angiography is consistent with that of conventional dose contrast agent examination,and can reduce the residual contrast agent and reduce the incidence of adverse reactions.
