BACKGROUND AND PURPOSE: Early CT signs in the deep middle cerebral artery (MCA)
territories have been reported to be seen at the initial period of ischemia. We attempted to …

AIM: To investigate how often early computed tomography (CT) signs are associated with
blood–brain barrier (BBB) disruption and result in haemorrhagic transformations …

The usefulness of CT and angiography for predicting the final ischemic brain damage
resulting from supratentorial ischemic stroke was evaluated in 36 patients. CT was …

PURPOSE To investigate the incidence and prognostic value of local brain swelling, the
extent of parenchymal hypodensity, and the hyperdense middle cerebral artery sign as …

Despite recent documentation of the utility of magnetic resonance (MR) in patients with
acute onset of neurologic deficit caused by acute ischemia (1), emergency computed …

During the first hours after acute ischemic stroke, the CT usually shows no abnormalities.
Therapeutic trials of ischemia in the middle cerebral artery (MCA) territory involves decision …

Background Occluded major intracranial arteries can spontaneously recanalize in patients
with acute ischemic stroke mainly due to embolic mechanisms. However, it remains …

The early CT finding of an hyperdensity of a portion of the middle cerebral artery
Hyperdense Middle Cerebral Artery Sign (HMCAS), in patients with supratentorial stroke, is …

PURPOSE To assess the reliability of detecting signs of hemispheric infarction on CT scans
obtained within 6 hours of the onset of symptoms. METHODS A neuroradiologist selected 12 …

Objectives: The 'hyperdense MCA sign'refers to an appearance of increased attenuation of
the proximal middle cerebral artery (MCA) that is often associated with thrombosis of the M1 …
