title: Power Doppler needle-induced fremitus for breast localization.
abstract: OBJECTIVE
  We attempted to identify the preoperative, sonography-guided breast localization technique which can be used in cases in which surgeons require the shortest incision route or exact localization of a lesion.
  
  
  METHODS
  We performed a phantom study using a lesion-in-breast model, investigating the concept that the flash artifact is induced at the tip of the vibrating needle on power Doppler images, before attempting any clinical applications. In view of the results achieved in the phantom study, we applied this technique to patients referred to our department over a 2-year period.
  
  
  RESULTS
  Of the 312 breast localizations in which we used this technique in 289 patients, all procedures were successfully performed without serious complications.
  
  
  CONCLUSIONS
  The vertical approach with the power Doppler needle-induced fremitus technique indicates the shortest incision route to and the exact localization of a breast lesion.
