Title: An evaluation of MRI-DWI and FLAIR on staging the cerebral infarction
Abstract: Objective It's an evaluation of MRI-DWI and FLAIR on staging the cerebral infarction. Methods Serial MRI-DWI and FLAIR scan were performed in 65 patients with cerebral infarction. The appearing time, extent and FLAIR scan were performed signals were analyzed. Results In super-acute stage apparent hyper-intense lesions were revealed on DWI, while no abnormality was found on FLAIR in demonstrating the hyper-intensity of lesions. In the later sub-acute stage the lesion signal began to decline. In the early chronic stage the lesions presented iso-intensity on DWI, when the lesion signal started to decline on FLAIR. After 30 day of episode, the lesions were iso-intense in most of the cases except hypo-intense lesions revealed in several cases. Conclusion DWI is a routine study in super-acute stag of cerebral infarction because of the good demonstration of the lesion extent, FLAIR is superior to DWI in investigation of the lesion in sub-acute and chronic stage, and FLAIR is also helpful in staging lesions in a case with multiple cerebral infarctions.
