[Neuroimaging in cerebral ischemia].

Area of Science:

• Neurology
• Radiology
• Vascular Medicine

Background:

• Cerebrovascular diseases, particularly stroke, require rapid and accurate diagnosis.
• Advances in neuroradiology have significantly improved stroke detection and management.
• Emerging treatments for acute brain ischemia necessitate familiarity with advanced imaging modalities.

Purpose of the Study:

• To critically review neuroimaging techniques for cerebrovascular diseases.
• To highlight the impact of neuroradiology on stroke diagnosis and management.
• To discuss the role of various imaging modalities in acute stroke.

Main Methods:

• Review of current literature on neuroimaging in cerebrovascular diseases.
• Analysis of the utility of computed tomography (CT) in acute stroke.
• Evaluation of perfusion- and diffusion-weighted magnetic resonance imaging (MRI) for stroke assessment.
• Discussion of functional imaging and angiography techniques.

Main Results:

• Computed tomography is the most accessible acute stroke imaging technique for Spanish neurologists.
• Early CT signs of infarction are critical for effective utilization in acute stroke.
• Perfusion- and diffusion-weighted MRI provide extensive information for acute stroke management.
• Functional and angiography techniques play a role in evaluating cerebrovascular diseases.

Conclusions:

• Neuroimaging is pivotal in the diagnosis and management of cerebrovascular diseases.
• Familiarity with advanced imaging techniques, including CT and MRI, is essential for neurologists.
• Future therapeutic decisions for acute stroke will increasingly rely on advanced imaging findings.
