Dynamic F-DOPA PET for Differential Diagnosis Between Recurrence and Radionecrosis of Brain Metastasis

"During the usual patient care protocol for the 18F-FDOPA TEP examination, a 10 min acquisition starts after a 15 minutes waiting period following the injection of the radiotracer. This allows the reconstruction of a single late image volume. In the framework of this project, the patient is placed in the machine at the time of injection so as to acquire early 18F-FDOPA uptake and then reconstruct intermediate image volumes in addition to the usual final volume.~The total duration of the patient's examination is therefore not changed."
