Imaging the Vasculitides.

Area of Science:

• Neurology
• Radiology
• Immunology

Background:

• Vasculitic disorders affect blood vessels, potentially impacting the brain and nervous system.
• Accurate diagnosis is essential for effective treatment and management of vasculitis.
• Neuroimaging provides critical insights into the neurological manifestations of vasculitis.

Purpose of the Study:

• To highlight the importance of neuroimaging in diagnosing primary and secondary vasculitic disorders.
• To discuss the various neuroimaging modalities used in vasculitis assessment.
• To emphasize the role of neuroradiologists in the multidisciplinary care of vasculitis patients.

Main Methods:

• Review of noninvasive neuroimaging techniques (e.g., MRI, CT).
• Discussion of invasive cerebral angiography for small vessel imaging.
• Integration of clinical deficits with imaging findings.

Main Results:

• Neuroimaging modalities accurately describe clinical deficits in vasculitis.
• Noninvasive methods offer lower risk and aid in understanding the disease process.
• Invasive angiography may be necessary for detailed visualization of small vessels.

Conclusions:

• Neuroimaging is vital for diagnosing vasculitic disorders.
• A combination of neuroimaging techniques provides a comprehensive understanding.
• Neuroradiologists are key members of the vasculitis care team, driving diagnostic innovation.
