摘要
目的:探讨低剂量CT头颈血管成像(CTA)与高场磁共振MRA对头颈部动脉狭窄的诊断价值。方法:选择经某院数字减影血管造影(DSA)技术检查确诊的100例头颈部动脉狭窄患者作为研究对象,时间设定2016年12月~2019年2月,并给予低剂量CT头颈血管成像与1.5T高场磁共振MRA检查,回顾性分析所有患者检查的临床资料。结果:本研究100例患者通过DSA检查可诊断出251支血管节段数,而通过CTA检查可诊断出250支,通过MRA检查可诊断出249支;CTA诊断敏感性、特异性、PPV、NPV分别为92.86%、87.50%、86.67%、93.33%,MRA诊断敏感性、特异性、PPV、NPV分别为85.71%、93.75%、92.31%、88.24%,两种检查方式的诊断效果比较,差异无统计学意义(P>0.05)。结论:对头颈部动脉狭窄患者均可采用低剂量CT头颈血管成像与高场磁共振MRA检查,各有优势,联合诊断准确性更高。
Objective:To evaluate the value of low dose CT head and neck angiography(CTA)and high field magnetic resonance imaging(MRA)in the diagnosis of head and neck artery stenosis.Methods:A total of 100patients with head and neck artery stenosis diagnosed by digital subtraction angiography(DSA)in a hospital were selected for the study.The time was set from December 2016to February 2019.Low-dose CT head and neck angiography and 1.5Thigh-field magnetic resonance imaging(MRA)were performed.The clinical data of all patients were analyzed retrospectively.Results:A total of 251vascular segments could be diagnosed by DSA in 100patients.250were diagnosed by CTA and 249by MRA.The sensitivity,specificity,PPV and NPV detected by CTA were 92.86%,87.50%,86.67%,93.33%,respectively.The sensitivity,specificity,PPV and NPV detected by MRA were 85.71%,93.75%,92.31%and 88.24%,respectively.There was no significant difference in the diagnostic effect between the two methods(P>0.05).Conclusion:Both low-dose CT head and neck angiography and high-field magnetic resonance imaging(MRA)can be used in the diagnosis of head and neck artery stenosis,each has advantages,and the combined diagnosis is more accurate.
