| 目的 应用高分辨率磁共振成像（HR-MRI）分析基底节区孤立性缺血性脑卒中的病因。方法 连续纳入2015年1月至2016年12月于我院住院治疗并完成大脑中动脉管壁磁共振成像的基底节区孤立性缺血性脑卒中患者15例，对患者临床及影像学资料进行分析。结果 血管评估结果提示，15例基底节区孤立性缺血性脑卒中患者中大脑中动脉无狭窄6例，轻度狭窄4例，中度狭窄2例，重度狭窄3例。HR-MRI检查提示10例患者病变侧大脑中动脉有斑块形成，其中7例为弧形斑块、3例为环形斑块。T1加权像增强检查结果提示8例患者斑块明显强化，1例轻度强化，1例无强化。结论 基底节区孤立性缺血性脑卒中病因复杂，HR-MRI检查可以清晰显示大脑中动脉的管壁及斑块情况，为病因判断提供帮助。 |

| Abstract: |
| Objective To investigate the pathogenesis of isolated ischemic stroke in basal ganglia using high resolution-magnetic resonance imaging (HR-MRI). Methods Fifteen consecutive patients with isolated ischemic stroke in basal ganglia, who received HR-MRI examination in our hospital between Jan. 2015 and Dec. 2016, were included in this study, and the clinical and imaging data were analyzed. Results Vascular evaluation results showed that 6 patients had normal middle cerebral artery, 4 had mild stenosis, 2 had moderate stenosis, and 3 had severe stenosis. HR-MRI examination showed that plaque formation of the middle cerebral artery in the lesion side was found in 10 patients, of which 7 patients had arc plaques and 3 had annular plaques. T1 weighted imaging showed that the plaques of 8 patients were obviously enhanced, the plaque of 1 patient was moderately enhanced, and the plaque of 1 patient was not enhanced. Conclusion The etiology of isolated ischemic stroke in basal ganglia is complex. HR-MRI examination can clearly show the wall and plaque of the middle cerebral artery, providing evidence for etiological judgment. |
