To review the epidemiology and pathophysiology of cerebral ischemic infarction. To expose the magnetic resonance imaging (MRI) protocol of study of ischemic stroke and review the usefulness of the different acquisition sequences. To establish the correlation between findings obtained in the MRI study and multimodal computed tomography (CT) images.

Ischemic stroke constitutes a pathology with a great social impact due to its frequency, mortality and potential physical sequelae, with a worldwide incidence of approximately 200 cases per 100,000 inhabitants/year according to the World Health Organization. It consists of an interruption in cerebral circulation that leads to a significant decrease in blood flow, associated with a neurological deficit. It is usually of thromboembolic etiology, produced up to 35% by occlusion of a large intracranial vessel (distal internal carotid artery, proximal middle cerebral artery or basilar...

Radiological tests used in the assessment of cerebral ischemic infarction are mainly multimodal computed tomography (CT) and magnetic resonance imaging (MRI). MRI has high sensitivity and specificity in the early detection of cerebral ischemia, although it is currently not considered a first-choice examination in the field of hospital emergencies due to its longer acquisition time and lower availability compared to CT. MULTIMODAL CT The objectives of multimodal CT in patients with acute stroke are: Rule out intracranial hemorrhage Differentiate dead tissue (core) from potentially salvageable...

An early diagnosis of ischemic stroke is essential in order to avoid both its possible physical sequelae and its associated mortality. In this aspect MRI shows a great sensitivity and specificity, highlighting the sequences weighted in diffusion in the evaluation of its evolutionary stage. Currently, multimodal CT is the radiological test used initially, so it is necessary to correlate the signs present in both techniques.
