Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP frontal portable view of the chest was obtained . The patient is rotated to the left and is likely kyphotic in position . Due to patient positioning , the examination is quite suboptimal . There are patchy bibasilar opacities , which could relate to atelectasis , but underlying consolidation is difficult to exclude . It is also difficult to exclude small bilateral pleural effusions . No large pneumothorax is seen . Mediastinal contours are difficult to assess due to patient positioning . Cardiac silhouette appears mildly enlarged . There are low lung volumes . Also , the right humeral head appears subluxed in relation to the right glenoid , not optimally evaluated on this study .
    OUTPUT:
    
Suboptimal study due to patient positioning . Recommend repeat with better patient positioning for better evaluation . Grossly , bibasilar opacities are seen , which could be due to atelectasis , however , underlying consolidation is not excluded . Right humeral head appears subluxed in relation to the right glenoid , not optimally evaluated on this study .
