低场强磁共振不同成像序列在急性脑梗死中的应用进展

Progress of Different Applications of Low-field Magnetic Resonance Imaging Sequences in Acute Cerebral Infarction

探讨低场强磁共振T1加权成像、T2加权成像、液体衰减反转恢复序列(FLAIR)和DWI(DWI)等不同成像序列在急性脑梗死中的诊断价值。DWI序列明显优于FLAIR序列和T1加权成像、T2加权成像序列,是急性脑梗死磁共振成像检查的首选序列,为临床提供客观依据并及时进行溶栓治疗,从而减少患者的病死率和致残率。现就低场强磁共振机在急性脑梗死的应用进展进行综述。

Low-field magnetic resonance of T1WI,T2WI,fluid-attenuated inversion recovery（Fluid attenuated inversion recovery,FLAIR） and diffusion-weighted imaging（diffusion weighted imaging,DWI） sequences in different imaging in the diagnosis of acute cerebral infarction are discussed.Serial DWI,which is obviously better than FLAIR sequences,T1WI,and T2WI sequences,is the first choice of MRI examination of acute cerebral infarction,to provide an objective basis for clinical and timely thrombolytic therapy,thereby reducing patient mortality and morbidity.Here is to review the application of low-field MRI machine in acute cerebral infarction.
