Low power requirements and transportability have enabled scanning outside the controlled …

Purpose—Our goal is to provide an overview of the current evidence about components of
the evaluation and treatment of adults with acute ischemic stroke. The intended audience is …

Radiological examination of the brain is a critical determinant of stroke care pathways.
Accessible neuroimaging is essential to detect the presence of intracerebral hemorrhage …
