Perifocal edema is specifically associated with malignancy and can therefore help to differentiate between benign and malignant breast disease. Furthermore, edema is associated with a higher grading and increased tumor size. These observations may be of prognostic value and should be considered in future investigations
Edema exhibits a clear signal difference to the surrounding tissue. This fact may be useful to quantify the amount of edema in the tissue analyzed.
Further study combining several morphologic and dynamic criteria is needed to fully estimate the full value of edema for MRM
