1. A method of comparing at least two images of a suspect area of a patient, the method comprising: providing at least two images of the suspect area; digitally overlaying the at least two images; performing a best-fit transformation of one image using a stored transformation algorithm to encourage the one image to approximately correspond to at least one detected attribute of the other acquired image; comparing the at least two images to determine whether a difference exists between an aspect of the one image when compared with the same aspect of the other image; and wherein subsequent to comparing the at least two images, a computer algorithm provides an output that describes the presence or absence of the difference between the at least two images.
