A (AIRWAYS)
Normal Chest X-ray Features:
1.Trachea: visible, midline, and straight
How to examine Chest X-ray :
Start at the top and follow the trachea
(1) Inferiorly. It should be in the midline. It divides at the carina .
(2) To give off the left mainstem bronchus.
(3) And the right mainstem bronchus
(4) On the left, the airway ends at the bifurcation of the left mainstem bronchus, where it splits into the upper lobe bronchus
(5) And lower lobe bronchus
(6)On the right, the right mainstem bronchus gives off the upper lobe bronchus
(7) and continues inferiorly as the intermediate bronchus
(8)The airway ends at the bifurcation of the intermediate bronchus, where it splits into the middle lobe bronchus
(9) And Lower lobe bronchus

Airways Demonstration in Normal Chest X-ray: Importance:
Importance of Airways Demonstration:
1. Diagnostic accuracy: helps identify respiratory and cardiovascular conditions
2. Baseline evaluation: establishes normal airway anatomy
3. Monitoring disease progression: compares changes over time
4. Therapeutic planning: guides bronchoscopic interventions
5. Complication detection: identifies pneumothorax, atelectasis
Airway Abnormalities Detectable on Chest X-ray:
1. Tracheal deviation or narrowing
2. Bronchial dilation or constriction
3. Airway wall thickening
4. Consolidation or nodules
5. Pneumonia or bronchitis
Clinical Applications:
1. Chronic obstructive pulmonary disease (COPD)
2. Asthma
3. Bronchiectasis
4. Cystic fibrosis
5. Lung cancer
Limitations of Chest X-ray:
1. Limited sensitivity for small airway disease
2. Overlapping structures obscure airway details
3. Unable to detect early lung disease
4. Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) may be necessary for detailed evaluation
Supplementary Imaging Modalities:
1. High-Resolution Computed Tomography (HRCT)
2. Magnetic Resonance Imaging (MRI)
3. Bronchoscopy
4. Pulmonary function tests (PFTs)
Radiological Signs:
1. Ring sign (tracheal narrowing)
2. Focal hyperinflation (bronchial dilation)
3.tram-track sign (bronchial wall thickening)
3. Gloved finger sign (bronchial dilation)
Reporting and Documentation:
1. Describe airway caliber and morphology
2. Note any abnormalities or deviations
3. Compare with previous studies (if available)
4. Recommend additional imaging or testing (if necessary)
