    INPUT: Frontal and lateral radiographs of the chest demonstrate continued opacification at the left lung base which appears to be atelectatic as no pleural effusion is seen in the lateral view . The study is however limited due to technique and should be repeated . The remainder of the left lung field as well as the right lung is clear . Cardiac silhouette is enlarged , not acutely . There is no evidence of pneumothorax . The lung volumes are decreased compared to the prior study , accentuating the cardiac contour .
    OUTPUT:
    
Poor quality image . No definite pneumothorax or pleural effusion . Recommend repeat study .
