Background

 

Stroke can be defined as an acute central nervous system injury with an abrupt onset, and is the third leading cause of mortality in developed countries, and also a major cause of morbidity.

 

It is a syndrome caused by disruption of the blood flow to part of the brain.

 

-Risk factors of stroke: high blood pressure (the most important one), cigarette smoking, diabetes, obesity, isquemic cardiopathy, atrial fibrillation...

 

-Types:

   - Hemorrhagic stroke (15%): rupture of a blood vessel, with injury to cells and sudden loss of focal brain functions.

   - Ischemic stroke (85%): due to occlusion of a blood vessel. It can be further divided into two groups: thrombotic and embolic strokes.

The goals of the imaging evaluation are to establish a diagnosis as early as possible and to obtain information for guidance on selecting the appropriate therapy.
