title: Sonohysterography: the utility of diagnostic criteria sets.
abstract: OBJECTIVE
  The objective of our study was to determine whether applying specific diagnostic criteria to the interpretation of sonohysterography would improve the diagnostic accuracy of the interpretation.
  
  
  METHODS
  This retrospective study included 200 consecutive patients who underwent both sonohysterography and a procedure that resulted in a positive pathologic diagnosis. The initial interpretation (reader 1) was performed at the time of the examination. Subsequently, a reviewer with limited expertise (reader 2) interpreted the sonohysterograms masked to both the original medical imaging report and the final pathologic diagnosis. Reader 2 used a set of standardized diagnostic criteria to aid in arriving at one of the following diagnoses: normal, endometrial polyp, endometrial hyperplasia, endometrial carcinoma, submucosal fibroid, adenomyosis, adhesions, or clots. These results were compared with the initial diagnostic report (reader 1) and the final pathologic findings.
  
  
  RESULTS
  Overall agreement with pathology findings was 76.7% for reader 1 and 84.9% for reader 2. Comparison of the readers' interpretations using the pathologic diagnosis as the reference standard showed that reader 2's interpretations, which were established using the diagnostic criteria set, were uniformly better than those of reader 2.
  
  
  CONCLUSIONS
  The application of standardized diagnostic criteria may enhance the diagnostic accuracy of sonohysterography.
