[The potentials and importance of imaging in large-vessel vasculitis].

According to the nomenclature of the Chapel Hill Consensus Conference, giant-cell arteritis and Takayasu's arteritis belong to the group of large-vessel vasculitis. Recognition of these diseases is primarily based on the clinical assessment and the use of various vascular imaging modalities. With regard to the latter one, significant technological advances have been observed in recent years, which allow not only to make a diagnosis but also to evaluate the extent of the disease and the degree of vascular inflammation. In addition, subsequent complications of vascular inflammation can be examined. Ultrasound, computed tomography, magnetic resonance imaging, and positron-emission tomography represent imaging modalities that are essential for recognizing affected patients and planning effective treatment and follow-up. The review of this topic may be of interest to a number of medical specialties that are potentially involved in the care of these patients. Orv Hetil. 2020; 161(23): 939-950.
