title: Cerebrospinal fluid fistula: detection with MR cisternography.
abstract: OBJECTIVE
  Our goal was to assess the role of MR cisternography in the examination of patients with suspected CSF rhinorrhea.
  
  
  METHODS
  MR cisternography was performed as a heavily T2-weighted fast spin-echo study with fat suppression and video reversal of the images in 37 patients over a 3-year interval. Twenty-four of the patients subsequently had exploratory surgery for fistula. Statistical analysis of the surgical results was compared with the findings at MR cisternography.
  
  
  RESULTS
  MR cisternography showed significant correlation with surgical findings, with sensitivity, specificity, and accuracy of 0.87, 0.57, and 0.78, respectively.
  
  
  CONCLUSIONS
  MR cisternography proved to be an accurate diagnostic imaging technique in the evaluation of suspected CSF rhinorrhea.
