Figure 2: A 63-year-old female with the right middle cerebral artery territory stroke. (a) Diffusion-weighted images show the right middle cerebral artery watershed infarcts. (b) Time-of-flight magnetic resonance angiogram demonstrates right middle cerebral artery and intracranial internal carotid artery occlusion. (c) Time-of-flight magnetic resonance angiogram shows the right internal carotid artery occlusion. (d) Rapid processing of perfusion and diffusion images indicating ischemic core (apparent diffusion coefficient <620) of 14 ml, hypoperfused area (Tmax >6 s) volume of 81 ml, mismatch volume, and mismatch ratio. (e) Preprocedure digital subtraction angiogram showing the right internal carotid artery occlusion. (f) Postprocedure digital subtraction angiogram image showing recanalization of the middle cerebral artery branches with stent in situ (arrow). (g) Computed tomography brain done after 24 h shows no infarct
