title: [Sex determination by studying head CT film].
abstract: OBJECTIVE
  To explore the methods for sex determination on head CT film.
  
  
  METHODS
  To establish the sex determination equations by binary regression analysis of cranial skeletal indices obtained on head CT film.
  
  
  RESULTS
  A single element equation by applying the index of the width of ansa capitis and a multi-element equation by applying multitude indices were established.
  
  
  CONCLUSIONS
  The equations for sex determination on head CT film were established.
