| 摘要 目的：探讨高分辨率核磁共振成像(magnetic resonance imaging，MRI)对颅内动脉粥样硬化斑块的诊断价值。方法：选择2016年1月至2018年6月在我院诊治的缺血性脑卒中患者134例作为研究对象，所有患者都给予数字减影血管造影(Digital subtraction angiography，DSA)与高分辨率MRI检查，记录颅内动脉粥样硬化斑块特征与分型，以DSA诊断为金标准，判断MRI的诊断价值(阳性预测值、特异度、灵敏度、阴性预测值)。结果：在134例患者中，高分辨率MRI显示未见斑块62例，Ⅰ型5例、Ⅱ型26例，Ⅲ型26例、Ⅳ型15例，与DSA诊结果一致124例，占比92.5%。高分辨率MRI与DSA诊断颅内动脉粥样硬化斑块的Kappa值为0.89，MRI对各分型的颅内动脉粥样硬化斑块的阳性预测值、特异度、灵敏度、阴性预测值分别为：I型87.0%、99.2%、95.8%和99.2%，Ⅱ型81.0%、98.5%、83.4%和98.5%，Ⅲ型82.7%、82.7%、84.0%和95.7%，Ⅳ型100.0%、100.0%、100.0%和100.0%。结论：高分辨率MRI用于诊断颅内动脉粥样硬化斑块的价值与DSA检查有很好的一致性，可反映硬化斑块的分型。 |

| ABSTRACT Objective: To investigate the values of high-resolution magnetic resonance imaging (MRI) in the diagnosis of intracranial atherosclerotic plaque. Methods: 134 cases of patients with ischemic stroke were selected from January 2016 to June 2018 in our hospital as subjects. All patients were given digital subtraction angiography(DSA) and high-resolution MRI examination, recorded the characteristics and classification of intracranial atherosclerotic plaque. The diagnostic value of MRI (positive predictive value, specificity, sensitivity, negative predictive value) was determined by taking DSA diagnosis as the gold standard. Results: In the 134 patients, high-resolution MRI showed there were no plaque in 62 cases, type I in 5 cases, type II in 26 cases, type III in 26 cases, and type IV in 15 cases, which were consistent with DSA diagnosis results in 124 cases that the rates were 92.5%, The Kappa value of high-resolution MRI and DSA in the diagnosis of intracranial atherosclerotic plaque were 0.89. The positive predictive value, Specificity, sensitivity and negative predictive value of MRI for each type were: I Type 87.0%, 99.2%, 95.8% and 99.2%, Ⅱ type 81.0%, 98.5%, 83.4% and 98.5%, Ⅲ type 82.7%, 82.7%, 84.0% and 95.7%, Ⅳ type 100.0%, 100.0%, 100.0% and 100.0%. Conclusion: The value of high-resolution MRI in the diagnosis of intracranial atherosclerotic plaque is consistent with that of DSA, which can reflect the classification of atherosclerotic plaque. |
