At TheUniversity of TexasMDAndersonCancerCenter, wehave used sonography (US) extensively for more than 2 decades to refine the local and regional staging of invasive breast cancer. Although magnetic resonance imaging is superior to all other imaging modalities in the measurement of the primary tumor anddetectionof additional foci ofmalignancy, in our experience US has shown sufficient accuracy in clinical practice to stage most invasive breast cancers. The exceptions are ill-defined tumors such as invasive lobular cancers and tumors in breasts containing extensive diffuse benign disease. Anadvantage ofUS is that multifocality ormulticentricity can be confirmed via USguided fine-needle aspiration within 15 minutes and the information share dimmediately with the patientand the breast surgeonormedicaloncologist. UShas alsoprovedindispensable in the evaluation of lymphatic spread because it can evaluate more nodal basins (e.g., the supraclavicular fossa and low neck) than magnetic resonance imaging can and because it can guide needle biopsy to confirm the status of any indeterminate node (including internal mammary nodes) within minutes.
