title: [To evaluate the examinations both colour Doppler flow image and CT for orbital pseudotumors].
abstract: OBJECTIVE
  To explore the values of colour doppler flow image(CDFI) technique and computer tomographic(CT) scan in diagnosising orbital pseudotumors.
  
  
  METHODS
  CDFI and CT were used for examining 67 cases of orbital pseudotumors demonstrated with surgery and pathaology. The results were treated with self-match design Chi-square test.
  
  
  RESULTS
  The diagnosis validities for 29 mass-type cases with CDFI and CT were 44.8% and 82.8%, respectively, with significant difference (chi 2 = 5.88, P < 0.05). The validities for 25 diffuse-type cases were 84.0% and 56.0%, respectively, with significant difference. (chi 2 = 4.0, P < 0.05). The validities for 19 mixture-type cases were 63.2% and 78.9%, respectively, with no significant difference (chi 2 = 1.63, P > 0.05). The diagnosis validities for all 67 cases were 63.0% and 72.7%, respectively, with no significant difference (chi 2 = 1.16, P > 0.05).
  
  
  CONCLUSIONS
  The diagnosis validities with both imaging methods were not different for diagnosis of orbital pseudotumors. But the values for diagnosing various pseudotumors were different. The validity with CDFI was superior to CT in diffuse type; CT was superior to CDFI in mass type; while the validity with CDFI and CT were not significant different in mixture type.
