title: [Comparison of diagnostic value between DR and MSCT in fracture and dislocation of foot and ankle].
abstract: OBJECTIVE
  To compare the diagnostic value between digital photography (DR) and multi-slice spiral CT (MSCT) in fracture and dislocation of foot and ankle.
  
  
  METHODS
  From August 2010 to August 2012, the DR and MSCT data of 52 patients with fracture and dislocation of foot and ankle were compared according to results of surgery or discharge diagnosis. There were 37 males and 15 females, aged from 15 to 49 years old. Wilcoxon signed rank test was used for statistical analysis.
  
  
  RESULTS
  The results of 52 cases of MSCT were matched with the postoperative or discharge diagnosis. A total of 172 fractures were found on MSCT and 98 fractures were found on DR, the results had significant difference in detecting fracture (V=1 081, P<0.05); A total of 24 dislocations were found on MSCT and 16 dislocations were found on DR,the results also had significant difference in detecting dislocation (V=21, P<0.05). Fractures of 6 cases with DR diagnosis were corrected and located by MSCT.
  
  
  CONCLUSIONS
  MSCT is significantly better than DR in diagnosis of fracture and dislocation of foot and ankle. The examination of two parts should be performed in DR. MSCT and multi-planar reconstruction (MPR) examination should be further performed if DR results are unclear or do not match with clinical symptoms, missed diagnosis and misdiagnosis can be avoided.
