title: Ultrasonographic evaluation of endometrial changes using computer assisted image analysis.
abstract: OBJECTIVE
  To examine the usefulness of a gray scale histogram and computer assisted image analysis software in assessing physiologic states of the endometrium with ultrasonography.
  
  
  METHODS
  Seventy patients at the Taipei Medical University-Wan Fang Hospital who matched eligibility criteria were categorized into one of three groups: (i) normal menstrual cycle, (ii) postmenopausal, and (iii) post incomplete abortion. Ultrasonography of the uterus was performed on each patient and the endometrium was analyzed with ImageJ image analysis software.
  
  
  RESULTS
  A statistically significant difference in signal intensity scores of the gray level histogram, represented as m(j), was found between the groups.
  
  
  CONCLUSIONS
  Ultrasonographic images analyzed using computer assisted image analysis software and gray level histogram are useful in assessing the physiological state of the endometrium.
