Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient has been intubated . Although it is difficult to measure the precise distance , the endotracheal tube closely approaches the carina and retracting the tube by approximately 2 cm is suggested . An orogastric tube courses into the stomach . There is better aeration at the right lung base . The pulmonary vascularity is again mildly prominent . It is difficult to exclude retrocardiac opacity noting slight blurring of the margins of the left hemidiaphragm , but this appearance may be due to difficulty in interpretation due to overlying soft tissue attenuation . The heart remains mildly enlarged .
    OUTPUT:
    
Status post endotracheal intubation . The endotracheal tube appears to closely approach the carina and retracting the tube somewhat is suggested for more optimal positioning . Improved aeration of the right lung base . Persistent cardiomegaly and mildly prominent pulmonary vasculature . Findings discussed with Dr . ___ .
