marker of acute intra-arterial thrombotic occlusion. However, the relationship between HAS …

Background and Purpose—In acute ischemic stroke, the hyperdense artery sign (HAS) on
noncontrast computed tomography (CT) is thought to represent intraluminal thrombus and …

Background and Purpose—The hyperdense middle cerebral artery sign (HMCAS) is a well-
established marker of early ischemia on noncontrast computed tomography of the brain …
