title: [A comparative study of HRCT and digital subtraction bronchography of bronchiectasis].
abstract: OBJECTIVE
  To assess the value of HRCT in the diagnosis of bronchiectasis at segmental level.
  
  
  METHODS
  29 cases (522 segments) with bronchiectasis doubted by clinical evaluation were selected and HRCT scan and digital subtraction bronchography (DSB) were performed.
  
  
  RESULTS
  HRCT and DSB showed a good identity in the diagnosis of bronchiectasis. Of 92 segments diagnosed as bronchiectasis in HRCT, 84 were agreed with DSB; Of 430 segments diagnosed as no bronchiectasis by HRCT, 425 were agreed with DSB. Sensitivity of HRCT is 94%, specificity is 98%. The main HRCT findings were cylindric and cystic bronchiectasis.
  
  
  CONCLUSIONS
  HRCT is superior to bronchography for bronchiectasis. It is the first choice of the image diagnostic modalities for the patients in whom bronchiectasis is suspected.
