Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are hyperinflated with flattening of the diaphragms . There is also biapical , right greater than left , scarring . Blunting of the posterior costophrenic angles may relate to hyperinflated lungs although trace pleural effusions are difficult to exclude . No pneumothorax is seen . The cardiac and mediastinal silhouettes are unremarkable .
    OUTPUT:
    
Hyperinflated lungs and biapical scarring suggest COPD . Slight blunting of the posterior costophrenic angles may relate to hyperinflation although trace pleural effusion is difficult to entirely exclude . CT is more sensitive in detecting small intrathoracic lesions .
