Analysis of Changes in Masses Using Contrast and Size Measures

摘要

One of the techniques used by radiologist to detect developing abnormalities is comparison of the current screening mammogram with previous ones. An observed change from a previous examination may bring attention to subtle signs of malignancy such as a new or growing mass or new or increasing calcifications that may have been overlooked otherwise [1]. The purpose of this study is to retrospectively determine mammographic changes in masses with respect to size and contrast. This information could furthermore be incorporated in CAD programs to improve the detection of masses and reduce the number of false-positives, just as in radiological practice.
