Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The radiographs were performed before and after the relocation of the endotracheal tube . The endotracheal tube is seen ending at the level of the carina in the first radiograph but after withdrawal its final placement is approximately 4 .5 cm above the carina . Otherwise , the lung volumes are low accounting for bronchovascular crowding . Bibasilar parenchymal streaky opacities are seen and appear more conspicuous than in prior . There is no pleural effusion or pneumothorax . The perimediastinal and hilar contours are unremarkable .
    OUTPUT:
    
1 . Final position of the endotracheal tube is 4 cm above the carina . 2 . Low lung volumes with new bibasilar opacities which may represent atelectasis versus aspiration .
