Computer-assisted three-dimensional reconstruction of the corticospinal system as a reference for CT and MRI.

abstract：PURPOSE:Flame-shaped pseudo-occlusion of the extracranial internal carotid artery (ICA) is a flow-related phenomenon that creates computed tomographic angiography (CTA) and digital subtraction angiography (DSA) findings that mimic tandem intracranial-extracranial ICA occlusion or dissection. We aim to determine the dia...
