Low-Dose CT Lung Screening

Low-dose CT examination of the chest for early detection of lung cancer, pulmonary nodules, emphysema, and other thoracic pathology. Recommended for current or former smokers (15+ pack-years), individuals with occupational lung exposure, or those with respiratory symptoms warranting imaging. No contrast required. Radiologist review and written report included.

Low-dose CT lung screening uses a dedicated low-radiation chest CT protocol to detect pulmonary nodules and early-stage lung cancer before symptoms develop. Large randomised trials have demonstrated that annual low-dose CT screening in high-risk smokers reduces lung cancer mortality by approximately 20% compared to chest X-ray, making it the most evidence-supported screening modality for lung cancer. The examination involves a brief breath-hold scan of the entire chest, typically completed in under 10 seconds. The low-dose protocol reduces radiation exposure to a level broadly comparable to natural background radiation over a few months. The entire appointment, including preparation and pre-scan consultation, takes approximately 30 minutes. The radiologist evaluates each scan for pulmonary nodules and categorises them using the Lung-RADS or Fleischner Society criteria, which stratify nodules by size, morphology, and growth pattern to guide follow-up recommendations. Incidental findings in adjacent structures — mediastinum, heart, thoracic spine, and upper abdomen — are also reported. ALTA Klinik Berlin offers lung CT without requiring a GP referral, which is practical for high-risk individuals who want direct access to screening. The report provides a structured assessment of findings and, where nodules are identified, clear guidance on recommended follow-up intervals. Patients with a significant finding can be referred to the appropriate specialist within the ALTA Klinik network or their own physician.
