Zusammenfassung
Ziele: The keyplayer transporters, metabolites and enzymes of the choline metabolism are regarded as biomarkers for cancer progression. MR Spectroscopy (MRS) and [11C]-choline PET allow for the in vivo characterization of this pathway, but there is only little evidence about the comparability and connection of both modalities on a biochemical level. Methode: For the murine glioma model, 5 × 103 SMA560 (spontaneous murine astrocytoma) cells were implanted into the brain cortex of syngeneic VM/Dk mice, which were grouped based on the post-implantation days 5 to 18. Dynamic microPET imaging and chemical shift imagi…
