Stem cells are a promising candidate for new therapeutic approaches of acute and degenerative disorders of the brain. MRI of prelabeled cells allows to follow their spatio-temporal dynamics after implantation, however this provides little information on cell graft function. We present here a novel bimodal approach of bioluminescence imaging (BLI) and 19F MRI to track 19F labeled, luciferase+ stem cells in the mouse brain. As the luciferase is only expressed in viable cells, BLI gives information on cell graft vitality in addition to the purely structural information given by 19F MRI.
