摘要/Abstract

摘要： 本研究探讨高分辨磁共振成像（MRI）3D黑血技术判断颈动脉斑块位置及预测脑卒中的应用价值。选取缺血性脑卒中患者68例（观察组），同时选取健康体检者50例作为对照组，给予高分辨MRI 3D黑血技术检查，分析两组黑血技术参数差异，同时采用ROC曲线分析参数预测脑卒中的价值。共检出颈动脉粥样硬化斑块82处；高分辨MRI 3D黑血技术颈动脉斑块检出率为95.12%；观察组颈动脉血管总面积（TVA）、管壁面积（WA）及管壁标准化指数（NWI）明显高于对照组（P<0.05）；观察组缺血侧TVA明显高于非缺血侧（P<0.05）；TVA、WA及NWI预测脑卒中的ROC曲线下面积分别为0.801、0.825和0.842（P<0.05）。高分辨MRI 3D黑血技术判断颈动脉斑块位置有较好的价值，颈动脉定量指标在脑卒中预测中有一定应用价值。

Abstract: This study discussed high-resolution magnetic resonance imaging (MRI) 3D to determine the location of carotid plaque and predict stroke. 68 patients with ischemic stroke (observation group) were selected, and 50 healthy persons were selected as the control group, the high resolution MRI 3D black blood technique was performed, the differences of technical parameters of black blood between the two groups were analyzed, and ROC curve analysis parameters were used to predict the value of stroke. A total of 82 carotid atherosclerotic plaques were detected. The carotid plaque detection rate of high-resolution MRI 3D black blood technique was 95.12%. The total area of carotid blood vessels (TVA), tube wall area (WA), and tube wall standardization index (NWI) were significantly higher than those in the control group (P<0.05). The ischemic side TVA was significantly higher than the non-ischemic side (P<0.05). TVA, WA and NWI predict stroke under the ROC curve areas of 0.801, 0.825, and 0.842, respectively P<0.05. High-resolution MRI 3D black blood technology has good value in determining the carotid plaque location, The carotid artery quantitative index has a certain application value in the prediction of stroke.
