Imaging acquisition technique influences interpretation of positron emission tomography vascular activity in large-vessel vasculitis

To determine the impact of imaging acquisition time on interpretation of disease activity on 18F-fluorodeoxyglucose positron emission tomography (PET) in large-vessel vasculitis (LVV) and assess the relationship between clinical features and image acquisition time. Patients with giant cell arteritis (GCA) and Takayasu's arteritis (TAK) were recruited into a prospective, observational cohort. After a single injection of FDG, all patients...
