Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A portable frontal chest radiograph demonstrates an endotracheal tube terminating approximately 2 cm from the carina , with low placement likely related to patient head positioning . The enteric tube is not well visualized , but appears to terminate within the proximal stomach . The heart remains mildly enlarged . Apparent mildly improved aeration of the right lung is likely due to minimally improved lung volumes . No new focal consolidation is identified . No pneumothorax is appreciated . There may be mild vascular congestion .
    OUTPUT:
    
Apparent mildly improved aeration of the right lung is likely due to minimally improved lung volumes with unchanged consolidations . No new focal consolidation identified .
