title: A study on the correlativity of MRI signal classifications with TCM syndromes in femoral head necrosis patients.
abstract: OBJECTIVE
  To probe into the relation between magnetic resonance imaging (MRI) signal classifications and TCM syndromes in femoral head necrosis patients, so as to provide reference for TCM diagnosis of this disease.
  
  
  METHODS
  Refering to the criteria for TCM syndrome types of necrosis of the femoral head described in "The Guiding Principles of Clinical Studies of New Chinese Drugs" and Shimizu and Mitchell's MRI signal classifications, MRI signal classifications between different TCM syndrome types were compared.
  
  
  RESULTS
  The Shimizu signal classification of different TCM syndrome types had statistically significant difference (P = 0.04); Both T2WI+fs and Mitchell signal classifications of different TCM syndrome types had no statistical by significant differences (P = 0.42 or P = 0.15).
  
  
  CONCLUSIONS
  There is a certain correlativity of TCM syndrome types of necrosis of the femoral head with T1WI signal classification of MRI. MRI signal classification may contribute to objectivity in TCM syndrome typing of this disease.
