| Question | Answer |
| Aspiration | Radiodense or radioaque outline
EF: soft tissue technique for upper airway (-) |
| Atelectasis | Radiodense lungs regions with shift of heart and trachea in servere cases
EF: Increase |
| Bronchitis | Hyperinflation and dominant lung markings of lower lungs
EF: none |
| Bronchiectasis | Radiodense lower lungs
EF: none |
| Chronic Obstructive Pulmonary Disease COPD | Depends on cause
EF: changes only in severe cases |
| Cystic Fibrosis | Increases radiodensities in specific lung regions
EF: increase with severe conditions |
| Dyspnea | (difficulty breathing)
Depending on cause
EF: dependent on cause |
| Emphysema | Increased lung dimensions, barrel chest, flattened diaphragm, radiolucent lungs
EF: Significantly decrease, dependent of severity |
| Epiglottitis | Narrowing of upper airway at epiglottic region
EF: soft tissue lateral technique (-) |
| Lung Neoplasm (Bengin- Hamartoma) | Radiodensities with sharp outlines; mass may be calcified
EF: none |
| Lung Neoplasm(Malignant) | Slight shadows in early stages, larger defined radioqaque masses in advanced stages
EF: none |
| Pleural effusion (Hydrothorax-in pleural cavity)
Empyema-fluid in pus
Hemothorax-fluid in blood | increased radiodensity, air-fluid levels, possible mediastinal shifts
EF: increase |
| Pleurisy | Possible air-fluid levels, or none with dry pleurisy
EF: none |
| Pneumonia (Aspiration, Bronchopneumonia, Lobar-pneumoococcal, Viral- interstitial | Patchy infiltrate with increased radio density
EF: none |
| Pneumothorax | lungs seem displaced from chest wall, no lung markings
EF: none |
| Pulmonary edea (fluid within lungs) | increased diffuse radiodensity
EF: increase in severe cases |
| Pulmonary emboli (sudden blockage of artery in lungs) | rarely demonstrated on chest radiographs except for possible wedge shaped opacity (Hampton's hump)
EF: none |
| Respiratory distress syndrome RDS
or Hyaline Membrane Disease HMD in children | Granular pattern of increased radiodensity throughout lungs, possible air-fluid levels
EF: increase without obscuring pathology |
| Primary TB | Small opaque spots throughout lungs; enlargement of hilar region in early stages
EF: none |
| Reactivation (secondary) TB | Regions of calcification with cavitations, frequently in area of upper lobes and apices with upward retraction of hila
EF: none or slightly increased |
| Anthracosis- black lung
(Occupational lung disease- pneumoconiosis) | Small opaque spots throughout lungs
EF: None |
| Asbestosis
(Occupational lung disease-pneumoconiosis) | Calcifications (radiodensities) involving the pleura
EF: None |
| Silicosis
(Occupational lung disease pneumoconiosis) | (distinctive pattern of scarring and dense nodules
EF: None |
