Correlation between anti-thyroid peroxidase antibody levels and diffuse thyroid uptake of 18 F-fluorodeoxyglucose in Hashimoto’s thyroiditis: a retrospective study

Background On 18F-fluorodeoxyglucose (FDG)-positron emission tomography (PET), diffuse uptake in the thyroid gland is often observed in patients with Hashimoto’s thyroiditis. In this study, we evaluated the factors associated with diffuse uptake by comparing Hashimoto’s thyroiditis patients with or without diffuse uptake in the thyroid.
