• Purpose of Review: Vasculitides are characterized by mostly autoimmunologically induced inflammatory processes of vascularstructures. They have various clinical and radiologic appearances. Early diagnosis and reliable monitoring are indispensable foradequate therapy to prevent potentially serious complications. Imaging, in addition to laboratory tests and physical examination,constitutes a key component in assessing disease extent and activity.

They have various clinical and radiologic appearances. Early diagnosis and reliable monitoring are indispensable foradequate therapy to prevent potentially serious complications. Imaging, in addition to laboratory tests and physical examination,constitutes a key component in assessing disease extent and activity. This review presents current standards and some typicalfindings in the context of imaging in vasculitis with particular attention to large vessel vasculitides. Recent Findings: Recently, imaging has gained importance in the management of vasculitis, especially regarding large vesselvasculitides (LVV). Recently, EULAR (European League Against Rheumatism) has launched its recommendations concerningthe diagnosis of LVVs. Imaging is recommended as the preferred complement to clinical examination. Color-coded duplexsonography is considered the first choice imaging test in suspected giant cell arteritis, and magnetic resonance imaging isconsidered the first choice in suspected Takayasu’sarteritis. Summary: Due to diversity of clinical and radiologic presentations, diagnosis and therapy monitoring of vasculitides mayconstitute a challenge. As a result of ongoing technological progress, a variety of non-invasive imaging modalities now playan elemental role in the interdisciplinary management of vasculitic diseases.…
