Video series launches: practical guide to CT and CT perfusion in acute stroke imaging

A new educational series on stroke imaging begins with a primer on patient presentation (focal neurologic deficits like weakness, aphasia, vertigo) and how CT and CT perfusion are used in the initial evaluation.

• This first video introduces core stroke symptoms and initial imaging modalities, including a detailed look at CT perfusion assessment.
• Designed for an educational audience; a foundational resource for trainees learning the essentials of emergency neuroimaging.
• Key limitation: This is an introductory video overview, not a source for specific quantitative performance data.
