title: [The Multi-detector-row CT angiography for diagnosis of spinal dural arteriovenous fistula].
abstract: OBJECTIVE
  Multi-detector-row CT angiography (MDCTA) is useful for diagnosis of spinal arteriovenous (AV) shunt. So we reported the role and pitfall of MDCTA based on our experience.
  
  
  METHODS
  From January 2007 to September 2011, 57 cases used MDCTA in our institution. We investigated 22 case of spinal dural AVF and 5 cases of epidural AVF.
  
  
  METHODS
  All cases were performed by Toshiba Aquilion 64. FOV was the whole spine, curved planar reconstruction along the spinal canal, sagittal and axial view obtained by multi-planar reconstruction.
  
  
  RESULTS
  MDCTA detected dilated the perimedullary vein in all cases and identified the level of segmental artery matching the result of DSA in 16 cases of spinal dural AVF (73%) and 1 cases of epidural AVF (20%).
  
  
  CONCLUSIONS
  MDCTA is useful for screening, and identifying the shunt point, but care needs to be taken concerning the particular pitfall of MDCTA.
