1. A computer-implemented method for generating a report that indicates regions of suspected pathology in a nerve, the steps of the method comprising: (a) providing a segmented nerve volume to a computer system; (b) generating with the computer system, a first histogram based on a cross-section through the segmented nerve volume; (c) selecting a threshold value based on the first histogram; (d) generating with the computer system, a second histogram based on image intensity values in the segmented nerve volume that satisfy a condition based on the selected threshold value; and (e) generating with the computer system, a report that indicates regions of suspected pathology in the segmented nerve volume, wherein the report is generated based in part on the second histogram and the segmented nerve volume.
