Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube tip is approximately 6 cm from the carina . An orogastric tube is with side port within the stomach . There are low lung volumes . The heart size is likely mildly enlarged . The aortic knob is calcified . There is widening of the superior mediastinum likely due to supine technique and low lung volumes . Crowding of the bronchovascular structures is present , but no definite pulmonary edema is noted . Ill - defined patchy opacities are noted within the left upper lung field as well as both lower lung fields , which could reflect areas of atelectasis , aspiration , or infection . No pleural effusion or pneumothorax is identified . There are no acute osseous abnormalities .
    OUTPUT:
    
1 . Endotracheal and orogastric tubes in standard positions . 2 . Ill - defined opacities in the left upper lung field as well as both lower lung fields . Findings could reflect atelectasis , infection , or aspiration , and continued radiographic followup is advised .
