Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The endotracheal tube ends 2 .5 cm above the carina . The nasogastric tube enters the stomach . There are diffuse nodular parenchymal opacities . For example in the right upper lung there is a 1 .5 cm nodule . The lung volumes and mild pulmonary vascular congestion have improved compared to the prior chest radiograph performed 1 .5 hours prior . The cardiac contours are obscured by the dense parenchymal opacities but the heart size is likely normal . No pneumothorax . Cervical hardware is noted .
    OUTPUT:
    
Endotracheal and nasogastric tubes are in appropriate position . If the endotracheal tube was advanced it would be too low . Compared to the prior chest radiograph the lung volumes have improved and the pulmonary edema has decreased . Diffuse nodular lung parenchymal opacities could represent residual edema , multifocal infection or nodules . Once the patient has stabilized , dedicated CT chest is recommended .
