Quantitative kinetic modeling of small animal PET imaging data
Quantitative kinetic modeling of small animal PET imaging data
Tutkimus
The main goal of our research is to provide quantitative modeling tools that enable kinetic analyses of animal PET imaging data. Tracer kinetic models can be exploited to measure blood flow, membrane transport, metabolism, and ligand-receptor interactions noninvasively and quantitatively in various animal disease models tailored for metabolic disorders, and neurodegenerative and neuropsychiatric diseases. Ongoing projects aim at translating preclinically achieved data into human PET imaging protocols to be used in research and clinical settings.
