    INPUT: Hypoinflated lungs with crowding of vasculature . No pleural effusion or pneumothorax . Heart size is top - normal and likely accentuated due to low lung volumes . Mediastinal contour , and hila are unremarkable . Limited assessment of the osseous structures is unremarkable . No displaced rib fracture .
    OUTPUT:
    
1 . No acute cardiopulmonary process . Specifically no displaced rib fracture . 2 . Although no fracture or other bone abnormality is seen , conventional chest radiographs are not appropriate for detection or characterization of chest cage lesions . Any focal findings should be clearly marked and imaged with either bone detail views or CT scanning .
