title: Application of intraoperative computed tomography in a neurosurgical operating theatre.
abstract: OBJECTIVE
  The authors describe their own experience in use of intraoperative computed tomography (CT) with the Siemens SOMATOM Sensation in 125 cases.
  
  
  METHODS
  Intraoperative CT of the head was most often used in functional neurosurgery for stereotactic planning in 32 cases and for control of deep brain stimulation electrode placement in 18 cases. In spine surgery, CT was used most often in spine stabilization to control the placement of implants.
  
  
  RESULTS
  The implant had to be corrected in 7 cases (17% of 41 procedures), and in those cases the need for a revision procedure was therefore avoided. Intraoperative CT was also widely used in emergency procedures and perioperative complications in 13 cases, for control of intraventricular catheter or Rickham port placement in 8 cases, for evaluation of extent of tumour resection in 4 cases, for verification of electrode placement during percutaneous trigeminal rhizotomy in 3 cases, for evaluation of decompression after cervical corpectomy and thoracic discopathy in 3 cases, in complex fractures in 2 cases and as angio-CT after aneurysm clipping in 1 case. There was no significant prolongation of procedure duration. Intraoperative CT proved to be safe for a patient and for personnel. During the three-year evaluation period, the increasing use and indications for intraoperative CT were noted. Integration of CT with navigation is planned in the near future.
  
  
  CONCLUSIONS
  Intraoperative CT is a very useful tool in spine surgery as well as in functional neurosurgery and neurooncology.
