Exclusion Criteria: * Participants with current or recent history (within 6 months prior to the MRI) of chemotherapy for cancer; * Neoadjuvant chemotherapy between MRI and confirmation of lesion outcome (study lesions must be biopsied prior to undergoing any chemotherapy); * Pregnant (if a female is of childbearing potential - defined as a pre-menopausal female capable of becoming pregnant - confirmation of pregnancy status per the site's standard of practice should be done prior to MRI); * Unwilling or not suitable to undergo MRI or use the contrast agent gadolinium.
