Stereotactic localization of breast lesions.

The author describes a method of localizing nonpalpable breast lesions by transferring measurements from craniocaudal- and lateral-view radiographs to the breast itself in order to determine needle placement. In the more than 100 attempted cases, the lesion has been specifically localized, usually within 1 cm of the needle tip. Percutaneous biopsy can be carried out with the first needle used as a guide wire for the biopsy needle.
