    INPUT: The study is limited due to rotation of the patient . Allowing for this limitation , there is no focal parenchymal opacity . Cardiomediastinal and hilar contours are unremarkable . There is no pleural effusion or pneumothorax . A catheter running parallel to the spine along the left hemithorax likely represents VP shunt , both ends are out of view . Another catheter underneath the left hemidiaphragm is incompletely imaged .
    OUTPUT:
    
No acute cardiopulmonary process .
