1. A system for generating a report providing information regarding a clinical diagnosis or prognosis from medical images, the system comprising:
a memory configured to store a plurality of a medical images of an upper extremity of a subject;
a processor configured to access the plurality of medical images of the upper extremity of the subject stored in the memory and configured to:
segment the plurality of images based on at least muscle, fat, and bone;
identify and correct images for scan coverage variance based on a function of a distance on a bone as a percentage of total length of the bone;
determine at least one of extra-muscular fat or intra-muscular fat using segmentation of the plurality of images;
quantify at least one of structural volume, muscle volume, or fat infiltration in the upper extremity of the subject using the segmentation of the plurality of images and the determined at least one of extra-muscular fat or intra-muscular fat; and
generate a report providing information indicating pre-surgical or a post-surgical diagnosis or prognosis for the upper extremity including at least the muscle volume or fat infiltration ratio.
