title: [Contrast-enhanced ultrasound findings of breast cancer].
abstract: OBJECTIVE
  To study the manifestation of breast cancers of different sizes in contrast-enhanced sonography.
  
  
  METHODS
  Eighty-four patients with breast cancers were examined by contrast-enhanced ultrasound. Among them, the tumor diameter was beyond 2.0 cm in 50 cases, and no greater than 2.0 cm in the rest cases. The time-intensity curve (TIC) on the enhanced images was analyzed quantitatively, and the relations between the type of TIC and the enhancement patterns of the tumors were analyzed.
  
  
  RESULTS
  The enhancement patterns of the breast cancers showed significant difference between patients with tumor diameter beyond 2.0 cm and those with smaller tumors (P<0.01), but the other parameters were comparable between the two groups (P>0.05).
  
  
  CONCLUSIONS
  The enhancement patterns of breast cancers differ between tumors with sizes over 2.0 cm and smaller tumors, and differential analysis is suggested in the diagnosis of breast cancer using contrast-enhanced ultrasound.
