摘要/Abstract

摘要： 本研究探讨急性脑梗死及颈动脉粥样硬化应用快速血管壁三维MRI (CS-3D MERGE)技术评估的价值。选取缺血性脑梗死患者68例作为观察组,同时选取短暂性脑缺血发作患者50例作为对照组,两组均给予CS-3D MERGE技术检查,分析两组大脑中动脉狭窄程度、斑块重构指数、强化程度及偏心指数差异,同时分析CS-3D MERGE判断观察组患者颈动脉狭窄程度及斑块性质。观察组大脑中动脉斑块重构指数和强化程度明显高于对照组(P＜0.05);重构指数、强化程度诊断脑梗死的ROC曲线下面积分别为0.839和0.671(P＜0.05);CS-3D MERGE诊断观察组颈动脉狭窄程度与数字减影血管造影(DSA)结果的Kappa值为0.825(P＜0.05),一致性好;CS-3D MERGE判断颈动脉粥样硬化斑块性质与术后病理结果Kappa值为0.789(P＜0.05),一致性好。急性脑梗死及颈动脉粥样硬化诊断中应用CS-3D MERGE技术有较好的价值。

Abstract: This study discussed the value of rapid three-dimensional MRI of vascular wall (CS-3D MERGE) technology assessment for acute cerebral infarction and carotid atherosclerosis. Chosen 68 patients with ischemic cerebral infarction as observation group and 50 patients with transient ischemic attack as control group, both groups were examined by CS-3D MERGE. Analyzed the differences of the degree of middle cerebral artery stenosis, plaque remodeling index, enhancement degree and eccentricity index between the two groups, and CS-3D MERGE was analyzed to determine the degree of carotid artery stenosis and the nature of plaque in observation group. The index of middle cerebral artery plaque reconstruction index and intensification degree in observation group were significantly higher than those in control group (P<0.05). The area under the ROC curve of reconstruction index and intensification degree in diagnosis of cerebral infarction were 0.839 and 0.671 respectively (P<0.05). In the observation group the Kappa value of CS-3D MERGE diagnosis of carotid artery stenosis and digital subtraction angiography (DSA) results were 0.825 (P<0.05), which showed good consistency. The Kappa value of CS-3D MERGE in determining the nature of carotid atherosclerotic plaque and postoperative pathological results was 0.789 (P<0.05), which showed good consistency. CS-3D MERGE has a good application value in the diagnosis of acute cerebral infarction and carotid atherosclerosis.
