Chest Computed Tomography for Pulmonary, Airway, and Pleural Disease Evaluation
This radiation-based X-ray imaging technique acquires high-resolution cross-sectional images of the full respiratory system, including the trachea, bronchi, lung tissue, pleural lining, and diaphragm, to detect structural and functional abnormalities not visible on standard 2D chest radiographs. The non-contrast exam is frequently ordered to evaluate clinical conditions including community-acquired and viral pneumonia, interstitial lung disease, pulmonary nodules, chronic obstructive pulmonary disease (COPD), pleural effusions, pneumothorax, and diaphragmatic paralysis, with minimal ionizing radiation exposure and no risk of contrast agent-related side effects.
This low-radiation non-contrast chest CT captures detailed cross-sectional images of the lungs, airways, pleura, and diaphragm to diagnose acute and chronic respiratory system conditions.

Understanding CT Scan of lungs
Computed Tomography provides detailed visualization of lungs. The procedure uses controlled radiation to create precise images with excellent anatomical detail.
Clinical Indications
This assessment detects pulmonary nodules, evaluates lung parenchyma, identifies respiratory infections, and stages thoracic malignancies.
What to Expect
The procedure typically takes 15 minutes. The examination is painless and non-invasive.
How to read the report
- Results reviewed by board-certified radiologist.
- Report transmitted to referring physician.
