Ultrasound or Mammography Guided Localization

Your doctor has requested an ultrasound or mammographically guided breast needle localization. The purpose of this procedure is to help the breast surgeon pinpoint the correct area in your breast for surgery. This is done by placing dye and usually a small wire at the point of the abnormality. A highly-trained medical team will oversee your procedure. This team will include an imaging physician and an imaging technologist .
