目的比较液体衰减反转恢复成像(FLAIR)、磁共振弥散加权成像(DWI)、磁共振血管成像(MRA)在脑梗死(CI)检查中的特点,为临床实践提供理论指导.方法选择CI患者70例,均行FLAIR、DWI、MRA检查,比较超急性期、急性期脑梗死检出率.结果 70例早期脑梗死患者大多数为多发病灶,占60％；超急性期22例,急性期48例.DWI对脑梗死的检出率最高,特别是在超急性期,检出率达到100％,明显高于FLAIR和MRA(x2=12.4,P＜0.05).结论在早期尤其是超急性期CI诊断方面,DWI优于FLAIR和MRA；FLAIR对皮层和脑室旁病灶显示更佳；MRA能检出梗死区供血血管病变.

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.
