The Clinical Impact of Using 18F-FDG-PET/CT in the Diagnosis of Suspected Vasculitis: The Effect of Dose and Timing of Glucocorticoid Treatment

Figure 3

Positive 18F-FDG-PET/CT scans (%) for vasculitis and the duration of glucocorticoid (GC) treatment (days). In our study population, 21 of 38 vasculitis patients had positive 18F-FDG-PET/CT finding. In patients scanned within 3 days of GC treatment, 77% had vascular 18F-FDG uptake suitable for vasculitis in comparison to 42% after 8 days of treatment.
