Can 18 F-FDG PET predict the grade of malignancy in thymic epithelial tumors? An evaluation of only resected tumors

Objective Although 18-fluorine fluorodeoxyglucose positron emission tomography (18F-FDG PET) is thought to be useful for predicting the histological grade of thymic epithelial tumors (TETs), it remains controversial. To date, just a few of many previous studies have included only resected cases. Therefore, we investigated 18F-FDG PET findings only in patients with resected TETs.
