Oncology – Tumor Targeting
We are specialists in tumor targeting studies, PSMA, SSTR-2 and other tumor markers. Here PET/CT MIP images of mice with LNCaP tumors show the comparison between [68Ga]PSMA-617 at 1 h and [55Co]PSMA-617.

Neuro – Metabolic Functional Connectivity
We have refined techniques to investigate whole brain functional networks in rats. Here, horizontal [18F]FDP PET images show changes in regional brain metabolism before and after chemogenetic interventions, these could also be pharmacological or other stimulations.

Neuro – Receptor Occupancy
Using tracers for dopamine D2 and serotonin 5-HT2a receptors we investigate drug occupancies and target engagement at available receptor targets. Here using [18F]Fallypride PET we show that the proposed inert drug Clozapine-N Oxide induce occupancy at the D2 receptors at higher doses.

Pharmacology – PK/PD and ADME studies
We do PKPD and ADME studies of radiolabeled compounds and, as in this case, [57Co]-4OAin nanoparticles.
