The Role of 18F Fluorodeoxyglucose Positron Emission Tomography Scanning in the Diagnosis and Management of Systemic Vasculitis

Primary systemic vasculitis is a group of heterogeneous disorders, characterized by inflammation of blood vessels causing end organ damage from ischemia, aneurysm formation or dissection. Delay in the early diagnosis owing to non-specific symptoms, lack of definitive serological tests, limited availability of biopsy and standard imaging tests pose significant challenge in the management of these diseases. 18F-fluorodeoxyglucose (FDG) positron...
