The use of positron emission tomography may be helpful in making the diagnosis of large vessel vasculitis, according to data presented recently.
The records from 20 patients who underwent fluoro-deoxy-glucose positron emission tomography (PET) scans to detect the presence of large vessel vasculitis (LVV) were studied retrospectively. Patients had a 3:1 female-to-male ratio and a mean age of 67 years. Prior to PET scans, the preliminary diagnosis was giant cell arteritis (GCA) or LVV in 15 patients and polymyalgia rheumatica in five patients.
