Anatomically constrained tractography aims to reduce the number of false positive streamlines by applying anatomically realistic priors. Grey matter-white matter interface is currently extracted based on T1 information requiring the availability of a T1 volume and its accurate co-registration with diffusion MRI data. Here we describe an alternative method based on multi-shell multi-tissue constrained spherical deconvolution that produces the interface without the need for T1. We go ahead and compare our method with the existing one and show a potential application.
