title: Predicting atypia inside endometrial polyps.
abstract: OBJECTIVE
  To evaluate the efficacy of color Doppler exploration for assessing atypia inside endometrial polyps.
  
  
  METHODS
  A prospective study was conducted in a tertiary university hospital. Eight hundred six patients with endometrial polyps were studied with color Doppler sonography, and the resistive index inside the polyp stalk was obtained. The patients were then referred for hysteroscopic resection, and pathologic analysis was performed.
  
  
  RESULTS
  Thirty-five polyps with sonographic indications of atypia were pathologically confirmed. Sonographic indications of atypia inside 16 polyps were not confirmed. Three nonquestionable endometrial polyps had atypia inside them.
  
  
  CONCLUSIONS
  Low Doppler resistance is highly predictive of atypia inside endometrial polyps.
