Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Comparison with prior studies is severely limited by patient positioning . Allowing for these differences in technique , there may be a small left pleural effusion and increasing retrocardiac atelectasis . The mediastinum is probably unchanged . Repeat radiographs with standard positioning are recommended when clinically indicated . The endotracheal tube ends 1 .8 cm from the carina . The right IJ CVC ends at the cavoatrial junction . The enteric tube ends within the decompressed stomach . ___ midline drains and a right pleural drain are in unchanged position . Dual chamber pacemaker leads projecting unchanged standard position . There is no focal consolidation , pneumothorax , or pulmonary edema .
    OUTPUT:
    
Limited study , allowing for this , probable small to moderate left pleural effusion and increasing retrocardiac atelectasis . All lines and tubes in appropriate position .
