目的 通过与DSA比较,评价三维黑血磁共振成像(3D-BB-MRI)对颈动脉粥样硬化性狭窄的临床价值.方法 同时对40例颈动脉狭窄患者行DSA和3D-BB-MRI检查,比较两者在评估颈动脉狭窄程度、病变累及范围、破溃斑块检出的差异.结果 以DSA为金标准,3D-BB MRI判断颈动脉狭窄的Spearman相关系数为0.965,以狭窄率70％为判断点,其灵敏度为93.1％、特异度为100％、准确度为95.6％和阳性预测值为100％.3D-BB-MRI显示溃疡的灵敏度为100％、特异度为93.9％、准确度为95.6％和阳性预测值为85.7％.3D-BB-MRI和DSA的病变累及范围分别为(18.4±8.2) mm和(14.0±6.2)mm,P＜0.05.结论 3D-BB-MRI能较准确地显示颈动脉狭窄程度、溃疡斑块,在显示病变累及范围方面具有优势,可辅助DSA为临床提供可靠、有价值的信息.

Objective To evaluate the value of 3D black-blood MR imaging (3D-BB-MRI) in evaluation of atherosclerosis by comparing with DSA.Methods Forty patients with carotid stenosis underwent 3D-BB-MRI and DSA.The degree of stenosis,lesion length and plaque ulcer on DSA and 3D -BB-MRI were independently assessed and compared.Results Compared with DSA,3D-BB-MRI showed a good consistency of stenosis with Spearman's r of 0.965.The diagnostic sensitivity,specificity,accuracy and positive predictive value were 93.1％,100％,95.6％ and 100％,respectively,when the 70％ stenosis was used as the cut-off value.3D-BB-MRI was proved to have high sensitivity (100％),specificity (93.9％),accuracy (95.6％) and positive predictive value (85.7％) for plaque ulcer.3 D-BB-MRI shown a larger lesion length measurement than DSA (18.4 ± 8.2) mm vs (14.0 ± 6.2) mm,P ＜0.05.Conclusions 3D-BB-MRI could provide an accurate depiction of carotid stenosis and plaque ulcer,and it is superior to DSA in detecting lesion length,which will be beneficial for clinical assessment with DSA.
