Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Bedside AP radiograph of the chest demonstrates persistent bilateral diffuse opacities , consistent with stable mild pulmonary edema . The lung volumes are lower on today 's study , exaggerating heart size . There is no pneumothorax or pleural effusion . Minimal bibasilar atelectasis is also seen . An endotracheal tube once again terminates no less than 3 cm above the carina . An orogastric tube courses to the stomach and inferiorly below the field of view .
    OUTPUT:
    
Persistent mild pulmonary edema , without appreciable vascular engorgement or cardiomegaly , raises suspicion of noncardiogenic causes . Given the patient 's history of HIV , and the similar radiographic appearance of atypical pneumonia , this finding should be correlated with clinical symptoms of infection , and followed closely with follow - up radiographs .
