Abstract: Cerebral ischemia accounts for 70%~80%. Magnetic resonance imaging (MRI) shows infarct focus efficiently, which plays an important role in the diagnosis of ultra-early stage of ischemia and the prediction of infarcts' change. This paper reviewed the recent advance in the effect of MRI on the diagnosis and prediction of cerebral ischemia.

Key words: cerebral ischemia, magnetic resonance imaging, diffusion weighted imaging, perfusion weighted imaging, T1 weighted imaging, T₂ weighted imaging
