Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP single view of the chest has been obtained with patient in semi-upright position . There is moderate cardiac enlargement . No typical configurational abnormalities identified . The pulmonary vasculature appears somewhat increased , but this is probably the result of a poor inspirational effort and crowded appearance of the vascular structures . The diaphragms are relatively high positioned indicative of poor inspirational effort . Hazy density on the bases probably mostly related to patient 's rather prominent adiposity . No conclusive evidence for pleural effusion or new acute infiltrates . No pneumothorax .
    OUTPUT:
    
Moderate cardiomegaly but no evidence of acute pulmonary abnormalities .
