title: Hemoptysis: comparison of diagnostic accuracy of multi detector CT scan and bronchoscopy.
abstract: BACKGROUND
  Hemoptysis is the expectorating of blood from the tracheobronchial tree or pulmonary parenchyma. There is conflicting information about usefulness of radiography, MDCT, and bronchoscopy for investigating site and cause of the bleeding in patients with hemoptysis. The present study attempted to evaluated efficacy of these methods for identifying hemoptysis' cause and etiology on 40 patients with the disease.
  
  
  METHODS
  A total of 40 patients with Hemoptysis who were referred to Golestan and Emam Khomeini hospitals were evaluated. Complete history of symptoms, volume and duration of Hemoptysis and demographic information were documented. Radiography, MDCT, and bronchoscopy were performed on all patients in order to investigate the site and cause of the bleeding.
  
  
  RESULTS
  Results showed MDCT had higher efficacy in identifying bleeding site than radiography, while efficacy of radiography and bronchoscopy or efficacy of MDCT and bronchoscopy weren't significantly different. In addition, sensitivity of MDCT (60%) for detecting cause of the bleeding was higher than that of radiography (25%) and bronchoscopy (32.5%).
  
  
  CONCLUSIONS
  The present study suggests MDCT as a suitable method in screening patients with hemoptysis, because it managed to detect site and causes of bleeding more efficiently than other methods. Additionally, we concluded that MDCT is an appropriate technique for diagnosing malignancies that cause hemoptysis in patients.
