Imaging Vasculitis with PET

Assessing disease activity in large vessel vasculitis can be a challenge. And as imaging techniques evolve, clinicians must evaluate how to harness new imaging modalities in clinical care. In an attempt to predict the progression of large vessel vasculitis (LVV), our next guest, Dr. Kaitlin Quinn, used the vascular activity seen on a fluorodeoxyglucose-positron emission tomography (FDG-PET) scan to determine if there is an observable association with angiographic change. Dr. Quinn, author of the study Association of 18F-Fluorodeoxyglucose–Positron Emission Tomography Activity With Angiographic Progression of Disease in Large Vessel Vasculitis, breaks down her study and its methods along with her observations and findings for us.
