摘要
目的:探究颈动脉CTA和超声在动脉斑块和狭窄患者中的诊断效果及影像学特点.方法:选取2018年9月至2019年9月我院就诊的颈动脉斑块和狭窄患者80例,所有患者均接受颈动脉超声及CTA检查,分别比较两种方法判断斑块性质和狭窄情况的准确度,并分析其影像学特点.结果:80例患者共160条颈动脉,两种方法斑块诊断阳性率均为68.75%,一致性为100%,两种方法对于软斑块及混合斑块性质分类差异无统计学意义(P>0.05),对于钙化斑块判定差异有统计学意义(P<0.05);颈动脉超声及CTA对于易损斑块的诊断阳性率分别为50.00%、36.36%,两者差异有统计学意义(P<0.05);两种方法对于颈动脉狭窄程度分类差别无统计学意义(P>0.05).结论:颈动脉彩超及CTA在颈动脉斑块的性质及狭窄程度方面互有优势,合理应用两种检测方法可以提高诊断符合率.
Objective:To investigate the diagnostic effect and imaging features of carotid CTA and ultrasound in patients with arterial plaque and stenosis.Methods:Eighty patients with carotid atherosclerosis and stenosis were enrolled in our hospital from September 2018 to September 2019.All patients underwent carotid ultrasound and CTA so as to determine the accuracy of plaque and stenosis,as well as its imaging characteristics.Results:There were 160 carotid arteries in 80 patients.The diagnostic yields of the two methods were both 68.75%and the agreement was 100%.There was no significant difference between the two methods in the classification of soft plaques and mixed plaques(P>0.05),and the difference in calcified plaque was statistically significant(P<0.05);the diagnostic yields of carotid ultrasound and CTA for vulnerable plaque was 50.00%and 36.36%,respectively,and the difference was statistically significant(P<0.05);There was no significant difference in the classification of carotid stenosis between the two methods(P>0.05).Conclusion:Carotid ultrasound and CTA have advantages in the nature and extent of carotid plaque.Reasonable application of two detection methods can improve the diagnostic accordance rate.
