The role of [18F]fluorodeoxyglucose positron emission tomography in thymic epithelial tumors
نویسندگان
چکیده
The purpose of this study was to systemically review the available literature regarding the diagnostic performance of positron emission tomography (PET) using 2-[18F]fluoro-2-deoxy-D-glucose ([18F]FDG) in patients with thymic epithelial tumors. We reviewed 13 studies that evaluated the diagnostic role of thymic epithelial tumors with [18F]FDG-PET. [18F]FDG-PET is a useful radiological modality for differentiating between thymomas and thymic carcinoma. However, [18F]FDG-PET may not be useful for differentiating low-risk thymoma and high-risk thymoma. One paper reported that [18F]FDG-PET has a predictive significance for treatment and prognosis in thymic epithelial tumors. Two papers reported that the degree of [18F]FDG uptake in thymic epithelial tumors is based on glucose metabolism. [18F]FDG-PET may have a further use for radiological differential diagnosis of thymomas and thymic carcinomas.

Objective(s): Considering the fact that the standardized uptake value (SUV) of a normal lung tissue is expressed as x±SD, x+3×SD could be considered as the threshold value to outline the internal tumor volume (ITV) of a lung neoplasm. Methods: Three hollow models were filled with 55.0 kBq/mL fluorine18- fluorodeoxyglucose (18F-FDG) to represent tumors. The models were fixed to a barrel filled w...
