New protecting group chemistry is used to greatly simplify imaging probe production. Temperature and organic solvent-sensitive biomolecules are covalently attached to a biotin-bearing dioxaborolane, which facilitates antibody immobilization on a streptavidin-agarose solid-phase support. Treatment with aqueous fluoride triggers fluoride-labeled antibody release from the solid phase, separated fr...
Several studies have noted benign thecoma‑fibroma tumors with positive F‑18 fluorodeoxyglucose (FDG) accumulation mimicking malignant ovarian tumors following F‑18 FDG positron emission tomography (PET). The present study analyzed four cases with false‑positive F‑18 FDG PET/computed tomography (CT) diagnoses of thecoma‑fibroma tumors as malignant tumors due to F‑18 FDG accumulation, compared wi...
Purpose of the Report—The objective was to compare F-18 fluorodeoxyglucose (FDG) and F-18 fluorothymidine (FLT) positron emission tomography (PET) in differentiating radiation necrosis from recurrent glioma. Materials and methods—Visual and quantitative analyses were derived from static FDG PET and static and dynamic FLT PET in 15 patients with suspected recurrence of treated ≥ grade II glioma ...
The goal of this article is to delineate indications for (18)F-FDG PET/CT pertaining to inflammation in the pediatric population, with emphasis on those that have been described in the literature. The limitations of (18)F-FDG PET/CT in this type of evaluation are also described, and the importance of using as low a dose as feasible is discussed. After reading this article, the reader should be ...
