DWI、FLAIR对超急性、急性脑梗塞的诊断价值

Diagnostic value of DWI and FLAIR in superacute and acute cerebral infarction

目的:探讨磁共振弥散加权成像(DWI)、液体反转恢复(FLAIR)成像序列对超急性、急性脑梗塞的诊断价值。方法:对56例超急性、急性脑梗塞患者的常规的MIR、FLAIR、DWI图象进行比较分析。结果:16例超急性脑梗塞患者DWI、FLAIR、T2WI阳性发现率分别为93.75%、60%、50%;40例急性脑梗塞患者DWI、FLAIR、T2WI阳性发现率分别为100%、90%、87.5%。结论:在超急性、急性脑梗塞对病灶的显示DWI优于FLAIR和T2WI,、而DWI和T2WI相比无显著差异。

Objective： To evaluate the diagnostic value of diffusion- weighted imaging and fluid attenuated inversion recovery in superacute and acute cerebral infarction patient. Methods：We analyzed 56 cases of acute cerebral ischemia patients in regular MRI,FLAIR and DWI imaging. Results：The positive rates of DWI,FLAIR and T2WI in 16 cases of superacute cerebral infarction patients were 93. 75%, 60% and 50%,respectively. The positive rates of DWI,FLAIR and T2WI in 40 cases of acute cerebral infarction patients were 100%, 90% and 87. 5%, respectively. Conclusion： DWI is superior to FLAIR and T2WI in displaying superacute and acute cerebral infarction. There is no difference between FLAIR and T2WI in displaying superacue and acute cerebral infarction.
