摘　　要：目的:本研究对磁共振DWI、T2WI、FLAIR对脑梗死患者临床评价价值及预后相关性进行研究。方法:对医院收治的脑梗死113例患者行DWI、T2WI、FLAIR序列扫描,分析不同成像序列对脑梗死的诊断优势。结果:脑梗死超急性期和急性期患者DWI信号强度高而T2WI信号强度弱,慢性期患者FLAIR信号强度高;DWI信号在超急性和急性期患者中较敏感,T2WI信号对亚急性患者较敏感,而FLAIR对超急性期患者较敏感;T1WI低信号,T2WI高信号,DWI梗死区显著高信号患者预后不良发生率最高。结论:磁共振DWI、T2WI、FLAIR对不同时期脑梗死患者临床评价与预后具有重要的参考价值。Objective: To study the clinical value of magnetic resonance DWI, T2WI and FLAIR in patients with cerebral infarction,and to study the correlation between clinical evaluation and prognosis. Methods: 113 patients with cerebral infarction were treated with DWI,T2WI, FLAIR sequence scanning, analysis of different imaging sequences on the diagnosis of cerebral infarction. Results: Super acute andacute cerebral infarction patients the signal intensity of DWI and T2WI signal intensity is weak, patients in chronic phase and flair signalstrength is high; DWI signal in the patients with ultra acute and acute phase sensitive, T2WI signal of subacute patients more sensitive, andflair in patients with hyperacute is sensitive; low signal intensity on T1WI, high signal intensity on T2WI, DWI infarct zone significantly highsignal in the prognosis of the patients adverse has the highest incidence rate. Conclusion: Magnetic resonance DWI, T2WI, FLAIR has animportant reference value for the clinical evaluation and prognosis of patients with cerebral infarction in different periods.
