摘要
目的探讨无创性影像检查对颈动脉狭窄的诊断价值。方法对42例临床疑为颈动脉狭窄的患者行彩色多普勒超声(CDFI)、磁共振血管成像(MRA)及数字减影血管造影(DSA)检查,以颈总动脉法(CC法)计算狭窄率。结果CDFI对颈动脉斑块的检出率明显优于MRA、DSA。以DSA检查结果为金标准,CDFI和MRA诊断颈动脉狭窄及闭塞的敏感性、特异性及准确性分别为90.9%vs 94.5%6、5.5%vs 86.2%和82.1%vs 91.7%。结论无创性影像检查(CDFI、MRA)在诊断颈动脉狭窄及闭塞方面具有互补作用,应该配合应用,可作为普查和筛选的手段。
Objective To evaluate the value of noninvasive images in diagnosis of carotid artery stenosis. Methods Forty-two patients with clinical suspected carotid stenosis were examined by color duplex flow imaging （CDFI） ,magnetic resonance angiography（MRA） and digital substrate angiography（DSA）. The percentage of stenosis was calculated by using common carotid method（CC）. Results The positive rate of carotid artery plaques in CDFI was superior to that in MRA and DSA. With the findings of DSA as gold standard, for CDFI and MRA in diagnosis of carotid artery stenosis and occlusion,the sensitivity,specificity and accuracy were 90.9% vs 94.5% ,65.5% vs 86.2% and 82.1% vs 91.7%, respectively. Conclusion Noninvasive images （CDFI, MRA） have mutual effect. CDFI and MRA cooperative use is necessary. CDFI and MRA may be the methods of general investigation and case selection in diagnosis of carotid artery stenosis.
