ACUTE ISCHEMIC STROKE IMAGING

Imagem AVC isquêmico agudo e Intervenção

This apk focuses on hyperacute ischemic stroke, which we define operationally as that early period after stroke onset when a significant portion of threatened brain is potentially salvageable.

The time period this encompasses will depend on many factors; it may only be a few minutes in some individuals or greater than 12 hours in others. In most people, this hyperacute period will encompass less than 6 hours when intervention is usually most

effective.

The authors believe that patients with acute ischemic stroke can benefit most from the earliest possible definitive diagnosis and rapid, appropriate treatment. In the setting of hyperacute stroke, imaging plays a vital role in the assessment of patients.

The most recent advances in imaging can identify the precise location of the occluded vessel, estimate the age of the infarcted core, and estimate the area at risk or the ‘ischemic penumbra’. This APLICATION ANDROID FOR RADIOLOGY will cover these modern imaging modalities; advanced computed tomography and magnetic resonance methods are considered in detail. These two modalities are emphasized because of their widespread availability and the rapid development of their capacities in the diagnosis of stroke. Only brief mention is made of other modalities because they are less widely available and less commonly used in the evaluation of hyperacute stroke patients.
