title: Ultrasonography as a guidance method in the evaluation of mammographically detected nonpalpable breast lesions of suspected malignancy.
abstract: OBJECTIVE
  To evaluate the role of ultrasonography (US) as a method of guidance for fine-needle aspiration biopsy or preoperative wire localization in the demonstration of nonpalpable mammographically detected breast lesions.
  
  
  METHODS
  A total of 168 nonpalpable mammographically detected breast lesions were examined by means of high-resolution real-time US.
  
  
  RESULTS
  US depicted: 55% of all the lesions (92/168); 88% of the circumscribed densities (45/51); 80% of the stellate densities (35/44); 47% of the asymmetric densities (7/15); and 9% of the microcalcifications (5/58).
  
  
  CONCLUSIONS
  US was useful in guiding needle biopsy or wire localization in most of the circumscribed and stellate breast lesions, even in fatty breasts. However, with the equipment that is currently available, US was of no value in localizing microcalcifications.
