目的探讨超急性期脑梗死的MRI表现,评价低场磁共振弥散加权成像(DWI)在超急性期脑梗死中的诊断价值。方法回顾性分析37例发病时间小于6h,临床拟诊脑梗死的患者,均行常规MRI和DWI扫描,将获得的图像进行对比分析。结果在DWI序列中超急性期脑梗死100%表现为高信号。结论低场磁共振DWI序列对超急性期脑梗死的诊断非常敏感,对指导临床早期治疗具有重大意义。
Objective To investigate the MRI findings of hyperacute cerebral infarction and evaluate the diagnostic value of low field magnetic resonance diffusion-weighted imaging (DWI) in hyperacute cerebral infarction. Methods A retrospective analysis of 37 patients with onset time of less than 6h, clinically diagnosed patients with cerebral infarction, were performed conventional MRI and DWI scan, the obtained images were compared. Results In hyperacute cerebral infarction at DWI, 100% showed high signal. Conclusion Low-field MRI DWI sequence is very sensitive to the diagnosis of hyperacute cerebral infarction, which is of great significance to early clinical treatment.
