研究目的: |
1.利用MR无创血管水交换磁共振成像(MR-VEXI)技术,描述脑卒中患者发病后不同时间点(如急性期、亚急性期、慢性期等)血脑屏障通透性的动态变化过程和特征。 2.分析脑卒中后血脑屏障通透性的动态演变与患者临床指标、神经功能恢复程度及预后(如脑水肿程度、出血转化风险、神经功能评分变化、并发症发生等)之间的潜在关联性。 3.初步评价基于MR无创血管水交换磁共振成像(MR-VEXI)监测脑卒中后血脑屏障通透性动态演变的临床应用潜力,为脑卒中患者病情评估、预后预测或治疗反应监测提供影像学依据。 |

Objectives of Study: |
1. Use MR non-invasive vascular exchange magnetic resonance imaging (MR-VEXI) to describe the dynamic changes and characteristics of blood-brain barrier permeability in stroke patients at different time points after onset, such as the acute, subacute, and chronic phases. 2. Analyze the potential associations between the dynamic evolution of blood-brain barrier permeability after stroke and clinical indicators, degree of neurological recovery, and prognosis—including extent of cerebral edema, risk of hemorrhagic transformation, changes in neurological scores, and occurrence of complications. 3. Preliminarily evaluate the clinical application potential of using MR-VEXI to monitor dynamic changes in blood-brain barrier permeability following stroke, providing imaging-based evidence for disease assessment, prognosis prediction, and monitoring treatment response in stroke patients. |
