Low-Dose Pulmonary CT

Low-Dose Pulmonary CT

What is a low-dose CT scan?

Computed tomography uses X-rays to develop high-resolution images. Thanks to modern computer programs, low-dose CT scans emit up to 90% less X-rays than conventional CT scans.

Who should undergo this examination?

  • Smokers: Smoking cigarettes is responsible for 90% of all cases of bronchial carcinoma. 
  • Second-hand smokers: Second-hand smoking leads to a higher risk of cancer. Among spouses of smokers, for instance, the risk of developing lung cancer is greater (20% higher for women, 30% higher for men, increasing with exposure).
  • Genetic predisposition: People with at least one parent suffering from bronchial carcinoma are two to three times more likely to develop lung cancer. 
  • Known exposure to asbestos: Chemicals such as asbestos cause bronchial carcinoma and mesothelioma.
  • Known lung scarring also represents an increased risk.
