The exact role of vascular imaging with respect to monitoring of disease activity and prediction of disease relapse has not clearly been defined in giant cell arteritis. For this reason, patients with giant cell arteritis who are enrolled in the GiACTA trial can participate in a positron emission tomography-computed tomography (PET/CT) substudy. Selected patients will undergo a PET/CT of the neck, chest, abdomen and pelvis after one year of treatment to scan the large arteries for radiographic evidence of vascular inflammation. The goal of this substudy is to determine the proportion of patients with radiographic activity and the correlation of radiographic findings with the risk of subsequent disease relapse.
