The Etiology of Intracranial Artery Stenosis in Autoimmune Rheumatic Diseases: An Observational High-Resolution MR Imaging Study

Intracranial arteries are injured and lead to heterogeneous disease courses when exposed to AIRD and cardiovascular risk factors. While atherosclerosis acceleration is common, vasculitis may further contribute to the early development of occlusion and multiple artery involvement. Varied intracranial arteriopathies may result in different outcomes.
