Breast MR has received a boost in popularity due to the recent recommendation of the American Cancer Society for high risk screening. However, improving specificity has remained a challenge. Studies have shown that the evaluation of morphology is an important factor in properly diagnosing a suspicious enhancing lesion. Currently, only qualitative measures are used in breast MRI lesion evaluation. This work presents the adaptation of several mammographic shape factors to breast MRI. Preliminary analysis indicates these shape factors have the potential to increase specificity. We are currently undertaking a more extensive patient study.
