1. A system for estimating a value of a diffusion tensor, said system comprising:

  • an MRI machine;

    a processor in data communication with the MRI machine;

    a computer-readable medium in data communication with the processor, the computer-readable medium having encoded thereon software for estimating a value of a diffusion tensor, said software comprising instructions for;

    obtaining, from a plurality of test subjects, DT-MRI data from which an initial estimate of the tensor can be derived;

    determining a first value indicative of intra-subject variation in said data;

    determining a second value indicative of inter-subject variation in said data; and

    at least in part on the basis of said first and second values, determining a subject-specific additive offset for adjusting said DT-MRI data.
