Whole-brain in-vivo measurements of the axonal g-ratio in a group of 37 healthy volunteers

Whole-brain in-vivo measurements of the axonal g-ratio in a group of 37 healthy volunteers

The g-ratio, quantifying the ratio between the inner and outer diameters of a fiber, is an important microstructural characteristic of fiber pathways and is functionally related to conduction velocity. We introduce a novel method for estimating the MR g-ratio non-invasively across the whole brain us...
