1. Lesion size, type and configuration play an important role in localization planning. 2. Localization of lesions with associated calcifications need to be performed under mammographic guidance, non-calcified single masses can be localized with ultrasound using a single wire. 3. Post-neoadjuvant therapy, the footprint of residual disease must be localized. 4. Localization of intraductal lesions: galactography and methylene blue injection followed by needle localization ensures excision of entire ductal system.   

This exhibit will review steps involved in planning successful image-guided preoperative needle localization. Case-based review will include: 1. Planning Stage: Determining approach, number and type of needles, need for bracketing or localization of the targeted lesion, by illustrating various lesion types and challenging lesions. 2. Procedure Stage: review of patient positioning, imaging steps and preoperative communication with the surgeon. MRI, ductogram and Tomosynthesis-guided localization. 3. Post-procedure Stage: specimen radiography in assessing successful excision, margin status and the need to obtain additional tissue. 4. Illustration of potential complications, including wire migration, fractured wire, clip migration during localization with management suggestions.
