title: [Thoracic CT scan in intensive care unit patients: information supplementary to thoracic radiography].
abstract: OBJECTIVE
  To assess the diagnostic value of thoracic CT-scans in comparison with conventional chest radiographs in ICU-patients.
  
  
  METHODS
  Chest radiographs and corresponding thoracic CT-scans of 25 consecutive surgical ICU-patients were reviewed and interpreted independently by two radiologists. We analyzed the additional information provided by CT-scans and the diagnostic and therapeutic relevance of these findings.
  
  
  RESULTS
  In 22 patients (88%), thoracic CT revealed 35 single additional findings, in comparison with the corresponding bedside radiographs. In 7 cases (28%), these findings (tube-malpositioning, mediastinitis, mediastinal abscess and pneumothorax) required modification of patient management. Of 7 patients with tube thoracostomy, 3 tubes were malpositioned, which was only depicted on CT-scans. In 10 of 21 cases (48%), pleural effusions could only be visualized by CT. 3 of 5 (60%) pneumothoraces were detected by CT-scans only. There were no significant complications during transport or CT-examination.
  
  
  CONCLUSIONS
  Thoracic CT may provide significant information in addition to plain chest radiographs, particularly when specific problems or questions, referring to the management of ICU-patients, arise.
