Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An endotracheal tube terminates 1 .7 cm above the carina . Left PICC is unchanged in position in the mid SVC . Lung volumes remain low , accentuating the size of the cardiomediastinal silhouette . Increased left basilar opacity . Moderate right pleural effusion is likely unchanged given differences in patient positioning .
    OUTPUT:
    
1 . Endotracheal tube is located 1 .7 cm above the carina . 2 . Increased left basilar opacity may reflect increased atelectasis or developing pneumonia . 3 . Unchanged moderate right pleural effusion .
