1. A method for displaying a computer-generated determination of the likelihood of malignancy of a lesion in a mammogram, including the steps of: providing a digitized image of the mammogram and displaying the digitized image; employing an input device to select a region of interest directly on the displayed digitized image; processing the digitized image using a computer processor so that classifier data of a characterization feature of the lesion in the user-selected region of interest are quantified, the classifier data comprised of a plurality of parameters; and displaying quantified classifier data of the characterization feature in the selected region of interest, the displayed classifier data assisting a user in determining the likelihood of malignancy of the lesion.
