3D demonstration of the neurovascular remodeling and angiogenesis in experimental stroke. 3D Δ R2 mMRA was performed at day 3 after middle cerebral artery occlusion on a Sprague–Dawley rat. The ischemic region was located in the right cortex. The vessel signals are coded in the green color. ( A ) a 3D outlook, ( B ) an axial section, ( C ) a sagittal section, and ( D ) a horizontal section of the ischemic region. More cortical penetrating vessels are seen in the lesioned area, representing the hallmark event, angiogenesis.
