Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size is normal . The mediastinal and hilar contours are normal . The pulmonary vasculature is normal . No focal consolidation , pleural effusion , or pneumothorax . There may be a right lower lung opacity which could represent pneumonia , however it may also simply be due to patient positioning . IVC is in the inferior cavoatrial junction . Left pleural thickening is better seen on recent CT scan .
    OUTPUT:
    
No definite evidence of aspiration . PA and lateral radiographic examination may be more convincing and is recommended if the patient can tolerate it .
