Colored map of blood volume (BV) in a patient with right breast cancer and omolateral palpable node. Both the primary tumor (outlined by region of interest [ROI] 5) and the target node (outlined by ROI 6) are visible on this slice. High values of BV are depicted both in the primary tumor and in the target node. At post-surgical pathology, the lymph node was determined to be metastatic.
