title: [Study on needling depth of Fengfu (GV 16) with CT].
abstract: OBJECTIVE
  To study on needling safe depth of Fengfu (GV 16) with CT, so as to provide reference for safe needling depth of Fengfu (GV 16) in clinical acupuncture treatment.
  
  
  METHODS
  Forty-one adult volunteers were divided into 3 groups, a thin person group, a moderate person group and a fat person group according to Luo's indexes, and computer-aided tomography (CT) was used to measure the needling depth of Fengfu (GV 16).
  
  
  RESULTS
  The safe depths of perpendicular needling of Fengfu (GV 16) were different for persons of different somatotypes. The safe needling depth was (27.73 +/- 3.45) mm for the thin person group, (30.78 +/- 2.90) mm for the moderate person group, and (33.39 +/- 4.27) mm for the fat person group.
  
  
  CONCLUSIONS
  The safe needling depth < or = the dangerous depth x 75% can be used for reference for the safe needling depth of Fengfu (GV 16) for different somatotypes persons.
