title: Diagnostic performance of 64-MDCT for blunt small bowel perforation.
abstract: OBJECTIVE
  The objective was to assess the diagnostic performance of 64-multidetector computed tomography (CT) for blunt small bowel perforation (BSBP).
  
  
  METHODS
  The study included 106 CT examinations of surgically proven blunt bowel and mesentery injuries (78 of BSBP and 28 of non-BSBP). CT diagnosis was based on detection of bowel wall discontinuity or extraluminal gas.
  
  
  RESULTS
  Accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of CT diagnosis were 84.0%, 79.5%, 96.4%, 98.4%, and 62.8%, respectively. Bowel wall discontinuity and extraluminal gas were detected on 19.2% and 74.4% examination, respectively.
  
  
  CONCLUSIONS
  CT diagnosis of BSBP is highly specific but not sensitive.
