    INPUT: An endotracheal tube is in appropriate position 4 .6 cm above the level of the carina . The lungs are hypoinflated with crowding of vasculature . No pleural effusion or pneumothorax . The mediastinum is mildly widened measuring 8 .9 cm however this study was re - read with the outside hospital CT scan up - loaded and the mediastinum is within normal limits . Heart size and hila are unremarkable . No displaced rib fractures .
    OUTPUT:
    
1 . Study was re-read once outside hospital CT scan was uploaded and apparent mediastinal widening is due to abundant mediastinal fat . 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 .
