Computed Tomography of the Bilateral Pulmonary Respiratory System: Lungs, Trachea, Bronchi, Pleura and Diaphragm

Published: August 9, 2026Updated: August 9, 2026

This low-radiation computed tomography exam captures high-resolution cross-sectional images of the full bilateral pulmonary respiratory system, including lung parenchyma, the trachea, segmental and subsegmental bronchi, pleural membranes, and adjacent diaphragm, with no required intravenous contrast for standard lung disease evaluation. It serves as a first-line diagnostic and monitoring tool for acute and chronic respiratory pathologies including community-acquired pneumonia, idiopathic pulmonary fibrosis, small pulmonary nodules, pleural effusions, tracheobronchial strictures, and diaphragmatic dysfunction secondary to underlying lung disease, and its minimal effective radiation dose allows for safe repeated imaging to track disease progression or response to therapeutic interventions over time.

Quick summary

This radiation-based computed tomography exam generates high-resolution cross-sectional images of the bilateral lungs, trachea, bronchi, pleural linings, and diaphragm to diagnose, stage, and monitor both acute and chronic pulmonary pathologies.

Understanding CT Scan of lungs

Computed Tomography provides detailed visualization of lungs bilaterally. 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
