Brief Summary:
The aim of this study is to compare the use of FDG PET/CT to Ga-68 HA-DOTATATE (abbreviated DOTATATE) PET/CT in patients with active giant cell arteritis (GCA) started on prednisone to understand if DOTATATE can identify more areas of active blood vessel inflammation than FDG.
Detailed Description:
The aim of this study is to prospectively evaluate the potential use of 68-Ga HA-DOTATATE PET/CT for detecting medium-large vessel inflammation in a small number of GCA patients with active disease, as compared to FDG PET/CT, and to understand if DOTATATE uptake correlates with disease activity. Fifteen patients with active GCA (either newly-diagnosed or recently relapsed disease) who are receiving glucocorticoids will be enrolled. Participants will undergo baseline FDG PET/CT and baseline DOTATATE PET/CT scan. Tracer uptake will be described in 8 major vascular territories. DOTATATE PET/CT will be repeated again in 6 months, and tracer uptake will be correlated to clinical disease activity, and medication use.
