Objectives:
The preclinical research group aim for better understanding and characterization of disease progression. Models of common major diseases are used for longitudinal investigations, including effects of treatment.
Focus areas are in vivo studies of cell metabolism using hyperpolarized 13C enriched substances in mammary cancer and ischemic heart disease, and ex vivo studies of brain tissue microstructure and connectivity using diffusion imaging. In addition, the possible correlation between aquaporin expression and periventricular diffusion in hydrocephalus is investigated.
Resources:
The group uses a 4.7 T pre-clinical Varian MR-scanner with newly installed strong gradients for the studies. A range of RF coils are available including special coils for 13C and other special nuclei. For preparation the group has a well equipped laboratory and MR compatible physiological monitoring equipment is available.
