Preoperative image-guided needle localization

(With Mammography or Ultrasound)
When a non-palpable lesion is detected in a screening mammogram or ultrasound, the radiologist should proceed to a specific technique for its preoperative localization. For more than a decade, the “Diagnostic Mammography Center” has been performing this needle localization technique. During this process local anaesthetic is administrated and under mammographic or ultrasound guidance, the radiologist proceeds to the accurate placement of the guide wire in the target of the lesion. Then, the patient is led to the operating room for excision of the lesion. Afterwards, the removed specimen is subjected to an X-ray or ultrasound examination to confirm that the lesion is correctly excised. According to the guidelines of the European Union, radiologists are responsible for this localization technique.
