Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Patient positioning is somewhat suboptimal , this limits assessment of the cardiomediastinal contour . In particular , the position of the tip of the right - sided PICC can not be definitively assessed but appears to be in the right atrium . Similar in appearance when compared to the prior study . There is increased prominence of the bilateral hila with perihilar airspace opacity consistent with pulmonary edema , this has increased slightly when compared to the prior study . Presumed small left pleural effusion . No right - sided pleural effusion seen . No pneumothorax seen .
    OUTPUT:
    
Suboptimal patient positioning limits assessment however there appears to be an increase in the degree of pulmonary edema when compared to the prior study . The tip of the right - sided PICC can not be evaluated but is likely in the right atrium .
