Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is again mildly enlarged but difficult to visualize on this film in its entirety . The aortic arch is again calcified . The lung volumes are low . Patchy perihilar opacification with indistinct pulmonary vascularity suggests mild vascular congestion or fluid overload . Otherwise , the examination is limited . It is difficult to exclude pleural effusions . There is no pneumothorax . Similar moderate relative elevation of the right hemidiaphragm is noted . Prominent lucency beneath the right hemidiaphragm appears very similar and is likely to reflect colonic interposition noting that the appearance is basically unchanged . There is a mildly prominent gas distended segment of bowel projecting over the right upper quadrant , potentially small bowel .
    OUTPUT:
    
Findings suggesting mild vascular congestion . Similar elevation of the right hemidiaphragm with lucency compatible with colonic interposition , noting lack of change . However , clinical correlation is suggested . There is also mildly dilated segment of probable small bowel projecting over the right upper quadrant of the abdomen . Correlation with abdominal symptoms , if any , is recommended .
