BACKGROUND AND PURPOSE: CT angiography (CTA) is widely used and may be the only
vascular imaging technique ordered for emergent evaluation of neurovascular disease. With …

A study was performed to evaluate the relationship between the imaging features and
clinical presentation of vertebral artery (VA) dissection. Twenty-two patients with 24 VA …
