MRI-guided preoperative 125 I seed localizations: Case report.

Preoperative nonwire localizations with 125 I seeds are performed using mammographic or ultrasonographic guidance. Current MRI-guided interventions in the breast are primarily limited to biopsies and wire localizations. Occasionally, nonwire localization with 125 I seeds is preferred, but the target is only well seen on MRI. This case report describes how MRI-guided preoperative two 125 I seed bracket localization was performed.
