A method for the non-invasive imaging of an anatomic tissue structure in
isolation from surrounding tissues, including: receiving from an input
device magnetic imaging data from a patient of the anatomic tissue
structure and surrounding tissues; segmenting the imaging data to isolate
the anatomic tissue structure imaging data from the imaging data for the
surrounding tissues; separating the anatomic tissue structure imaging
data into data populations corresponding to tissue microstructures;
constructing an image from the imaging data for at least one of the
tissue microstructures; and storing or displaying the image. An apparatus
embodying the disclosed method is also described, as well as a method for
the quantitative measurement of a nerve tissue suspected of
demyelination.
