Abstract:
Objective To explore the value of diffusion weighted imagine(DWI) and magnetic resonance angiography(MRA) for the clinical significance in acute cerebral infarction in the early stage.Method The results of DWI and MRA and traditional CT and routine MRI in 30 patients with acute cerebral infarction were analyzed.Result Ultra-acute and acute cerebral infarction could be shown on DWI,which may not be shown on CT and T 2.WI.The focus that were shown on T 2.WI were more clearly shown on DWI.Focus and degree of intracranial vascular lesion could be detected rapidly.Conclusion DWI and MRA are sensitive for diagnosis in the early stage of acute cerebral infarction.Cerebral constitution and cerebral vessels can be shown by DWI and MRA,thus offering reliable imaging data for thrombolytic therapy.
