title: Accuracy of the mammographic report category according to BIRADS.
abstract: OBJECTIVE
  To determine the accuracy and predictive value of the mammographic report according to the BIRADS categories in Songklanagarind University Hospital.
  
  
  METHODS
  Mammograms of 1000 women who came to Songklanagarind University Hospital from June 1998 to September 1999 were reported and placed in category 1 for negative results, category 2 for benign lesions, category 3 for probably benign lesions, category 4 for suspicious lesions and category 5 for highly suspicious lesions. Accuracy was determined by either histology or by unchanged follow-up mammography within 24 months.
  
  
  RESULTS
  The total accuracy was 97.8%, sensitivity 62.5% and specificity 98.1%.
