ReviewUsefulness of Different Imaging Methods in the Diagnosis of Cerebral Vasculopathy.
Assessment of cerebral vasculopathies is challenging and requires understanding the utility of different imaging methods. Various techniques are available to image the vessel lumen, each with unique advantages and disadvantages. ⋯ Digital subtraction angiography remains the gold standard but is invasive, while VW-MRI provides a non-invasive way of assessing vessel wall pathology. Conventional brain MRI has high sensitivity in the diagnosis of vasculitis but findings are nonspecific.

Vasculitis is characterized by the inflammation of blood vessels. Vasculitides refers to the different forms of vasculitis, often classified according to the size of the blood vessel that is involved. Vasculitis may occur as a primary process or secondary to many systemic diseases. This topic provides an overview of the clinical features, diagnosis, and classification of the different forms of vasculitides.

Childhood cerebral vasculitis is a condition that affects the blood vessels in the brain of children and is rare but life-threatening. Imaging plays a crucial role in the diagnosis and monitoring of the disease. This article describes the classification, diagnostic algorithm, and various imaging modalities used in the evaluation of childhood cerebral vasculitis and the imaging findings associated with primary and secondary vasculitis. Understanding the imaging features of this condition can assist in early diagnosis, effective treatment, and improve outcomes.

Vasculitides are characterized by inflammation of the vessel wall, with their categorization relying on clinical and paraclinical manifestations, vessel type, size, distribution, histological attributes, and associated conditions. This review delves into the salient neuroimaging hallmarks of central nervous system vasculitis associated with the most prevalent systemic diseases and highlightings potential pitfalls and diagnostic confounders.
