Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An improved position of the endotracheal tube , with the tip now terminating approximately 5 cm above the carina . There is persistent opacification at the left lung base , since the earlier study on ___ , likely reflecting a small left pleural effusion and atelectasis . There is a recurrent opacity at the right lung base , which is also most compatible with atelectasis . No large pleural effusion or pneumothorax is detected . There is increased mild pulmonary vascular congestion / interstitial edema . The cardiac silhouette is incompletely evaluated in the setting of left basilar opacification . The mediastinal and hilar contours are within normal limits and unchanged . There is mild calcification of the aortic knob .
    OUTPUT:
    
1 . Improved ET tube position , terminating 5 cm above the carina . 2 . Persistent left pleural effusion and atelectasis and probable right basilar atelectasis . 3 . Mild pulmonary vascular congestion / interstitial edema is mildly increased .
