Abstract: Objective To compare the clinical value of fluid attenuated inversion recovery imaging (FLAIR),magnetic resonance diffusion-weighted imaging(DWI) and magnetic resonance angiography(MRA) in diagnosis of early cerebral infarction.Methods 70 cerebral infarction patients were chosen.They underwent FLAIR,DWI and MRA examination.Results 70 patients with early cerebral infarction mostly were multiple lessions accouting for 60％.Supper actue period had 22 cases and acute period had 48 cases.DWI had the highest detection rate of cerebral infarction,particularly in the hyperacute period the detection rate reached 100％,which was significantly higher than the FLAIR and MRA(x2 =12.4,P ＜ 0.05).Conclusion Especially in the early diagnosis of hyperacute cerebral infarction,DWI is superior to FLAIR and MRA.FLAIR showed better on the cortex and periventricular lesions,MRA can check out the blood vessel lesions in the infarction area.
