title: [MSCT perfusion analysis of nasopharyngeal cancer].
abstract: OBJECTIVE
  To study MSCT perfusion imaging of nasopharyngeal cancer and its differentiated diagnosis.
  
  
  METHODS
  Thirty cases with nasopharyngeal cancer performed multi-detector CT perfusion examination. Among them, there were 6 cases of 25 post-radiotherapy patients performed perfusion imaging with CT scan. Nasopharynx perfusion parameters include blood flow (BF), blood volume (BV), mean transit time (MTT) and permeability surface (PS).
  
  
  RESULTS
  Compared with normal region of nasopharynx, BF, BV and PS in nasopharyngeal cancer increased significantly, while MTT has not significant difference between these two areas.
  
  
  CONCLUSIONS
  Nasopharynx perfusion parameters (BF, BV and PS) measured with CT were significantly altered in nasopharyngeal cancer. There was important appliance value in differentiated diagnosis of nasopharyngeal malignant neoplasms and evaluation of outcome of radiotherapy of nasopharyngeal cancer.
