title: [Quality assurance of rapid on-site evaluation of CT-guided fine-needle aspiration cytology of lung nodules].
abstract: BACKGROUND
  The methods available for the diagnosis of lung cancer include radiologic, cytologic and pathologic procedures.
  
  
  OBJECTIVE
  The aim of this study was to determine the quality assurance of CT guided fine needle aspiration cytology of lung nodules.
  
  
  METHODS
  Cytology results were rated to 4 categories (positive; suspicious; negative; not representative). All cytology reports were compared with the final histology diagnosis.
  
  
  RESULTS
  A total of 128 patients underwent CT-guided percutaneous fine-needle aspiration biopsy cytology (63 males; 65 females; mean age 62.8 years). Smears were adequate in 99 cases and inadequate in 29 cases. The average diameter of the nodules was 3.28 cm. Thirty three (25.6%) of the cases were histologically verified and 2 falsely negative and 2 falsely positive cases were detected. The sensitivity and the positive predictive value were 88.8% and 88.8%, respectively. Pneumothorax developed in 7 (5.4%) cases.
  
  
  CONCLUSIONS
  These results suggest that CT-guided transthoracic fine needle aspiration cytology has a high diagnostic accuracy and an acceptable complication rate. The auditing valves of the results meet the proposed threshold values.
