1. A method for analyzing a subject medical image containing at least a first body part having symmetrical properties with a second body part, comprising:

  • determining, using a processor, a line of symmetry between the first body part in the subject medical image and the second body part;

    analyzing, using the processor, regions of the first and second body parts on opposite sides of the determined line of symmetry for differences; and

    only when one or more differences between one of the regions of the first body part in the subject medical image relative to a symmetric one of the regions of the second body part are found,retrieving, from a database, at least one set of a plurality of specific metrics from a plurality of sets of metrics stored in the database, each of the sets of metrics stored in the database being derived from an anomaly or a non-anomalous region in an associated one of a plurality of historical medical images such that at least one set is derived from an anomaly of an associated historical medical image and at least one set is derived from a non-anomalous region of an associated historical medical image, each of the metrics in each set of metrics being a different measurement of the associated historical medical image;

    determining, using the processor, a plurality of specific metrics from each of the regions of the first body part in the subject medical image, each of the metrics being a different measurement of the region of the first body part in the subject medical image;

    comparing, using the processor, each of the determined metrics from each of the regions of the first body part in the subject medical image to a respective one of the metrics of the retrieved at least one set of the plurality of metrics from the database to determine a degree of similarity therebetween;

    creating, using the processor, a contour map based on the determined degree of similarity between the plurality of determined metrics from each of the regions of the first body part in the subject medical image and the retrieved at least one set of the plurality of metrics from the database; and

    displaying the created contour map on the subject medical image on a display.
