Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient has been intubated and the tip of the ET tube terminates in the right main stem bronchus and should be retracted approximately 5 cm for appropriate positioning . There is interval opacification of the left lung base compatible with atelectasis . A small left pleural effusion can not be excluded . The right lung is relatively clear with interval improved opacity at the right lung base from the most recent prior study . No pneumothorax is detected . There is mild pulmonary vascular congestion / interstitial edema , which is unchanged . The cardiac silhouette is incompletely evaluated in the setting of left basilar opacification . Mediastinal and hilar contours are within normal limits and stable with tortuosity of the thoracic aorta and partial calcification of the aortic knob .
    OUTPUT:
    
1 . Right mainstem intubation . The ET tube should be retracted approximately 5 cm . 2 . Interval left basilar collapse . Small left pleural effusion is likely present . 3 . Persistent mild pulmonary vascular congestion / interstitial edema .
