Percutaneous localization of breast lesions: experience with the Frank Breast Biopsy Guide.

The advantages of a wire localization guide for nonpalpable breast lesions have been demonstrated in 16 patients. The hooked end will not move after placement when the external end is anchored by a strong clamp. The malleable wire permits post-insertion compression mammograms to be performed. With the wire left in situ, orientation of the biopsy specimen with post-localization mammograms can guide the surgeon if further resection is necessary.
