摘要
目的探讨低场强MRI中FIJAIR技术对脑梗塞的诊断价值。方法回顾性分析15例急性脑梗塞病人的MRI影像资料，评价病变的显示范围、边界、与周围组织的对比度、检出病灶的数目及病灶的大小。结果FALIR序列对病变的显示范围、与周围组织的对比均优于常规T2/WI。结论FIJAIR序列对于显示靠近脑表面及侧脑室周围的梗塞灶，以及鉴别新、旧梗塞灶明显优于常规T2WI序列，有很高的临床应用价值。
This thesis examines the diagnostic value of FLAIR technology at low field MRI in cerebral infarction. By analyzing the MRI data of 15 acute cerebral infarction patients and evaluating the scope and boundary of pathological changes, the contrast between pathological area and normal tissues, the number and size of pathological focus, this thesis reports the findings that serial FLAIR imaging is superior to the regular T2WI in terms of detecting the scope and boundary of pathological changes and showing the contrast between pathological area and normal tissues. Finally, this thesis concludes that FLAIR is distinctly superior to T2WI in detecting the focus of cerebral infarction near brain surface and the lateral ventricle and distinguishing the new focus from the old one, therefore has a high clinical value.
