Answer

Answer

Morphology of a lesion is the most important criterion for distinguishing between benign and malignant lesions. Breast MRI specificity may be improved by analyzing the pattern of contrast enhancement on dynamic images. Breast cancers tend to enhance early, whereas normal breast tissue enhances slowly.
