Clinical features of atlantoaxial involvement in patients with rheumatoid arthritis using F-fluorodeoxyglucose-positron emission tomography with computed tomography.

Introduction/objectives: Cervical spine involvement is one of the most serious complications in rheumatoid arthritis (RA). The study aim was to assess the clinical significance of atlantoaxial (AA) joint involvement detected by F-fluorodeoxyglucose (FDG)-positron emission tomography (PET) with computed tomography (CT) in patients with RA.

Method: A prospective cross-sectional study was conducted to evaluate AA joint involvement detected by FDG-PET/CT in consecutive RA patients from December 2017 to February 2022.

Effect of drugs containing glucose on FDG-PET image quality.

Objective: Patients often take prescription drugs for various diseases or complications that contain several grams of glucose. However, the effect of these glucose-containing medications on the image quality of F-18 fluorodeoxyglucose positron emission tomography (FDG-PET) has not been established. This study aimed to evaluate the effect of taking drugs containing glucose before an FDG-PET on the PET image quality.
