Indications for targeted breast Ultrasound after a mammographic evaluation
• To evaluate a palpable abnormality further. In patients presenting with palpable breast masses, even if the mammogram results are negative, a targeted sonographic evaluation of the palpable area is a necessary part of the evaluation.
• To characterize a mammographic finding or abnormality. For example, if there is a new or enlarging mass seen on mammography, sonography is needed to characterize the mass. If the mass is demonstrated to be a cyst on sonography, nothing further needs to be done. But, if there is an enlarging or new solid mass, a biopsy is needed. As the mass is visible on sonography, the biopsy may be performed under ultrasound guidance.
