The ability of tracking peripheral nerves in foot could be of great benefit for a number of investigations, which include traumas, diabetes and infections. Previous approaches to nerve tracking have employed diffusion tensor imaging DTI. One limitation of DTI is the low signal-to-noise ratio due to short T2 (~30ms at 3T) of water protons in nerves. Here, we propose a novel approach to nerve tracking, which exploits the difference in MT ratio between muscle and foot nerves.
