Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An endotracheal tube terminates approximately 1 cm above the carina . There is also an orogastric tube that terminates in the gastric cardia . The heart appears mild - to - moderately enlarged ; although it is difficult to compare differences in technique , the size is probably increased . There is also some widening of the vascular pedicle suggesting fluid overload . Although there is mild asymmetry with greater opacification of the right lung and left , diffuse bilateral opacification is present , partly favoring the central areas . However , there is no definite pleural effusion and no evidence for pneumothorax .
    OUTPUT:
    
New diffuse bilateral opacification , although mildly asymmetric . Cardiomegaly , perhaps somewhat increased . Differential considerations include acute respiratory distress syndrome stemming from pneumonia , pulmonary edema or diffuse pneumonia . However , given how mild the pneumonia appeared only three days ago and rapid onset of diffuse opacification with cardiomegaly , pulmonary edema may be favored . Clinical correlation is recommended , however . Low positioning of endotracheal tube and proximal positioning of nasogastric tubes , which could be repositioned somewhat for more optimal positioning if clinically indicated .
