摘　　要：目的:评价CT减影技术对脑动静脉畸形的检出率和影像征象。方法:病例资料搜集时间为2021年9月~2023年11月,从本院收治的脑动静脉畸形患者中抽选66例展开系统研究,按照随机数表法为原则均匀分组,每组各33例,对照组接受常规CT血管造影检查,观察组接受CT血管造影减影技术检查,分析两组影像技术的检出结果及各组图像质量分级,分析影像征象的特点。结果:观察组诊断后的检出率为96.97%(32/33),其结果明显比对照组的检出结果78.79%(26/33)更高,差异有统计学意义(P<0.05);观察组诊断后的图像质量达标率为93.94%(31/33),而对照组的图像质量达标率为75.76%(25/33),两组测定结果对比有统计学差异(P<0.05)。结论:临床针对脑动静脉畸形患者的诊断检查选择CT减影技术能获得较高的检出率,并且检出图像质量好,影像征象特点典型、突出,便于临床诊断和治疗。Objective:To evaluate the detection rate and imaging features of CT subtraction imaging technique in cerebral arteriovenous malformations.Methods:The case data collection period was from September 2021 to November 2023.66 cases of cerebral arteriovenous malformations treated in our hospital were selected for a systematic study.They were evenly divided into two groups based on the principle of random number table,with 33 cases in each group.The control group underwent conventional CT angiography,while the observation group underwent CT angiography with subtraction imaging technique.The detection results and image quality grading of the two groups were analyzed,and the characteristics of imaging features were evaluated.Results:The detection rate after diagnosis in the observation group was 96.97%(32/33),which was significantly higher than the detection rate of 78.79%(26/33)in the control group,and the difference was statistically significant(P<0.05).The image quality compliance rate after diagnosis in the observation group was 93.94%(31/33),while in the control group,it was 75.76%(25/33),showing a statistically significant difference between the two groups(P<0.05).Conclusion:The use of CT subtraction imaging technique in diagnostic examinations for patients with cerebral arteriovenous malformations can achieve a higher detection rate and good image quality,with typical and prominent imaging features,facilitating clinical diagnosis and treatment.
