About

Longitudinal imaging in patients with large vessel vasculitis to predict further disease course

Full description

This explorative longitudinal prospective observational study is to explore different aspects of vessel wall characteristics as detected by magnet resonance imaging (MRI) techniques and positron emission tomography/computer tomography (PET/CT) in patients with large vessel giant cell Arteriitis (LV-GCA) for their usefulness as predictive factor for future giant cell arteritis (GCA) relapse. It analyses parameters in PET/CT and MRI in patients with GCA at treatment stop which correlate with GCA relapse within the first 6 months after treatment stop.

Patients included in the established local GCA database (BARK) will be screened for eligibility. Aortal imaging is performed during routine care according to established guidelines at diagnosis and during Follow Up at least every two years and before treatment stop.
