Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study was designed to assess vascular wall inflammation in patients with large vessel vasculitis by positron emission tomography and magnetic resonance imaging (PET/MRA). The study has a 12-month follow-up period. After completing the baseline clinical assessment, laboratory test and PET/MRA assessment, the intervention protocol will be determined by clinicians. The patients will visit the clinic every 1-2 months according to their specific conditions. Clinical assessment, laboratory test and PET/MRA re-examination will be completed at 6 and 12 months after treatment.
