Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is mildly enlarged . The aorta is tortuous and calcified . The mediastinal and hilar contours are otherwise unremarkable within limitations of technique . There is no evidence for pleural effusion or pneumothorax . There is a hazy right basilar opacity , possibly developing pneumonia versus atelectasis . Projecting over the left mid lung are two suspected small discrete nodules . Streaky basilar opacities may be due to minor atelectasis . The bones appear demineralized .
    OUTPUT:
    
1 . Patchy right basilar opacity , possibly pneumonia , new since the prior study ; patchy atelectasis could also be considered . Clinical correlation is advised . 2 . Persistent suspected small nodules in the left mid lung probably correlating with prior findings .
