In vivo follow-up of rat tumor models with 2-deoxy-2-[F-18]fluoro-D-glucose/dual-head coincidence gamma camera imaging.

Unlabelled: Before studying the impact of 2-deoxy-2-[F-18]fluoro-D-glucose (FDG) imaging with a dual-head coincidence gamma camera (DHC) for the follow-up of animal tumor models, we wanted to optimize this technique.

Methods: Three different animal tumor models (osteosarcoma, melanoma, and breast cancer) were studied after FDG injection. Dynamic and dual time point FDG/DHC imaging were studied from one hour to five hours postinjection.
