Large vessel vasculitis (LVV) causes vascular inflammation, leading to serious complications such as aneurysm formation and stroke. It is difficult to identify the inflammation of the vessel wall by the current imaging methods, thus affecting the timing of treatment and selection of treatment options. Improved examination methods to determine disease activity are highly needed to guide treatment.
