Abstract
A Gd3+ based paramagnetic dextran conjugate has been developed, which enables the tracking of neuroanatomical connectivity in the brain by both MR and optical imaging. Cell studies demonstrated that the synthesized tracer was efficiently internalized into neuronal cells and transported toward the axons. Furthermore, our preliminary in vivo experiments revealed efficient transportation of the conjugate, thereby proving its applicability for neuroanatomical studies by T1-weighted MRI. Initial in vivo experiments in rodents demonstrated the significant potential of this method.
