CXR (PA View) - Systematic Interpretation

Technical Adequacy

• Projection: PA erect view
• Rotation: Mild rightward rotation (asymmetric clavicular heads relative to spinous processes)
• Inspiration: Suboptimal - approximately 8 posterior ribs visible (ideally 9-10), causing mild crowding of bronchovascular markings in lower zones
• Exposure/Penetration: Adequate - thoracic vertebrae visible through cardiac silhouette

Systematic Findings

• Mild thoracic scoliosis with right convexity
• Ribs, clavicles, and scapulae intact - no fractures or lytic lesions
• Normal chest wall soft tissue; female breast shadows overlying lower lung fields

• Trachea midline superiorly; slight rightward deviation distally (related to scoliosis and prominent aortic arch)
• Mediastinum not widened
• Aortic knob is prominent with mild wall calcification - consistent with degenerative/atherosclerotic change

• Cardiothoracic ratio within normal limits (<50%)
• Left and right cardiac borders well-defined
• No cardiomegaly

• Both hila normal in size and density
• No hilar lymphadenopathy or mass

• Mild diffuse increase in interstitial markings in mid-to-lower zones bilaterally - likely accentuated by low lung volumes, but cannot fully exclude mild chronic bronchitic change
• No focal consolidation, nodule, or mass
• No pneumothorax

• Both hemidiaphragms smooth and well-defined; right appropriately higher than left
• Both costophrenic angles are sharp and clear - no pleural effusion
• Normal gastric air bubble under left hemidiaphragm; no sub-diaphragmatic free air

Impression

1. Mild thoracic scoliosis (right convexity)
2. Suboptimal inspiratory effort - crowding of lower zone markings
3. Prominent, mildly calcified aortic arch - age-related atheromatous change
4. No acute cardiopulmonary pathology - no consolidation, effusion, pneumothorax, or cardiomegaly

Note: This interpretation is AI-assisted and should be correlated with the patient's clinical history, symptoms, and reviewed by a qualified radiologist for formal reporting. The image appears to be photographed off a lightbox/monitor rather than a direct digital export, which may reduce fine detail.
