Aim of this work is to perform a punctual optimization of RARE parameters for 19F MRI studies of labeled neuronal stem cells. This approach is based on relaxation times estimation and numerical simulations. The optimization approach was evaluated in different biological environments at 11.7T MRI scanner.A correct optimization strategy increases the sensitivity of 19F MRI technique.
