18 F-click labeling and preclinical evaluation of a new 18 F-folate for PET imaging

18 F-click labeling and preclinical evaluation of a new 18 F-folate for PET imaging

BACKGROUND The folate receptor (FR) is a well-established target for tumor imaging and therapy. To date, only a few 18 F-folate conjugates via 18 F-prosthetic group labeling for positron emission tomography (PET) imaging have been developed. To some extent, they all lack the optimal balance between efficient radiochemistry and favorable in vivo characteristics. METHODS A new clickable olate p...

Imaging infection and inflammation in children with (18)F-FDG PET and (18)F-FDG PET/CT.

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 ...

Facile Preparation of a Thiol-Reactive (18)F-Labeling Agent and Synthesis of (18)F-DEG-VS-NT for PET Imaging of a Neurotensin Receptor-Positive Tumor.

UNLABELLED Accumulating evidence suggests that neurotensin receptors (NTRs) play key roles in cancer growth and survival. In this study, we developed a simple and efficient method to radiolabel neurotensin peptide with (18)F for NTR-targeted imaging. METHODS The thiol-reactive reagent (18)F-(2-(2-(2-fluoroethoxy)ethoxy)ethylsulfonyl)ethane ((18)F-DEG-VS) was facilely prepared through 1-step r...
