Il contributo della PET/TC con 18F-FDG nelle vasculiti dei grossi vasi: applicazioni e limiti della metodica nella pratica clinica

Our literature review revealed that 18F-FDG PET/CT is a useful tool for diagnosing vasculitis (especially when the symptoms of the disease are non-specific); guiding biopsy procedures (areas with high glucose consumption); evaluating disease extension; and monitoring treatment responses. The main limitations of this method are the relatively low spatial resolution of the tomograph, which can lead to false-negative results in the presence of small-vessel vasculitis, and risk of false positive results, especially those related to the presence of atherosclerosis and to post-treatment vascular remodeling.
