Brain images after the onset of cerebral infarction. A: Noncontrast brain computed tomography revealed a “dot” sign in the right middle cerebral artery (MCA; arrow) seen as a dot in the sylvian fissure. B: Brain magnetic resonance angiography (MRA) showing an occlusion of the right MCA (arrowhead) on the day of the stroke. C: Brain MRA 3 days after the stroke showing blood flow of the damaged area of the brain.
