FDG-PET/CT in venous thromboembolism

Purpose Venous thromboembolism (VTE) is common; deep venous thrombosis (DVT) and pulmonary embolism (PE) are the most common presentations. VTE may arise from anywhere in the entire venous bed and the diagnosis may be difficult. VTE is a dynamic disease, inflammation is key, and 18F-Fluorodeoxyglucose positron emission tomography/computer tomography (FDG-PET/CT) has been proposed in the evaluation of VTE to detect thrombi in any anatomic location, to differentiate acute from chronic VTE, and to differentiate bland VTE from tumor thrombosis. The aim of this systematic review was to assess if the potential uses of FDG-PET/CT in VTE are described and documented in the literature and to appraise the literature.
