The purpose of this study is using SWI, DWI and 3D GR2-based micro-MRA to assess the relationship between them and stroke evolution in rats with middle cerebral artery occlusion (MCAO) during progression of stroke. Our preliminary finding demonstrates that the combination of SWI, DWI and 3D GR2-based micro-MRA provides additional information for evaluation of rat brain with acute ischemic stroke, and may have a potential to contribute to determining the penumbra and predicting of the stroke prognosis, as well as further quantitative measurements.
