title: Intrathecal administration of gadopentetate dimeglumine for MR cisternography of nasoethmoidal CSF fistula.
abstract: OBJECTIVE
  Accurate diagnosis and localization of dural defects associated with CSF fistulas are difficult and often involve multiple imaging studies performed at the appropriate clinical moment. Our purpose was to assess the utility of intrathecal administration of gadopentetate dimeglumine for MR cisternography of patients with CSF fistula suspected clinically to arise from defects in the nasoethmoidal regions.
  
  
  CONCLUSIONS
  MR cisternography was useful for evaluating patients with rhinorrhea and suspected CSF fistula. It depicted the fistula site in most patients. No adverse effects were found in any patient.
