Interventional procedures in diseases of the breast: needle biopsy, pneumocystography, and galactography.

This article discusses the roles of mammography-guided needle biopsy of the breast, pneumocystography, and galactography in further defining breast lesions that have been detected with mammography. For each procedure, indications for its use, proper technique, complications, interpretation, and role in clinical practice are described. Use of these procedures is warranted for some patients to provide detail beyond that available with mammography and sonography.
