Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An endotracheal tube terminates about 3 .5 cm above the carina . An orogastric tube in passes into the stomach although its tip is not visible , lying beyond the inferior margin of the imaged field of view . The cardiac , mediastinal and hilar contours are probably within normal limits , but difficult to assess given AP portable technique and low lung volumes . Patchy opacities at each medial lung base are probably due to atelectasis . Otherwise , the lungs appear clear . There is no definite pleural effusion .
    OUTPUT:
    
Limited assessment suggesting mild basilar atelectasis with low lung volumes . Endotracheal tube in suitable position .
