title: [Comparison of ultrasound-guided mammotome and Tru-cut biopsy needle in diagnosing breast masses].
abstract: OBJECTIVE
  To compare the diagnostic value of ultrasound-guided mammotome and Tru-cut biopsy needle in diagnosing breast masses.
  
  
  METHODS
  Retrospective analysis was performed in 214 patients with breast masses obtained separately by mammotome or Tru-cut biopsy needle guided by ultrasound, and analyzed by pathological examination. The success ratios of sample choosing and the coincident ratios of pathological diagnosis were compared.
  
  
  RESULTS
  The success ratios of sample choosing for mammotome and Tru-cut biopsy needle were 100% and 90%, respectively. The coincident ratios of pathological diagnosis of mammotome and Tru-cut were 98. 7% and 90%, respectively. There was significant difference in the 2 groups (P < 0.05).
  
  
  CONCLUSIONS
  Mammotome is a useful method and superior to Tru-cut biopsy needle in the diagnosis of breast masses.
