Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is borderline in size . The aorta is mild to moderately tortuous . A smooth convexity to the right upper lateral mediastinum is most commonly due to tortuosity of the great vessels . The lungs appear clear . There is no pleural effusion or pneumothorax . Air beneath the medial left hemidiaphragm is probably due to gastric air , but in addition , there are distended loops of small bowel that are partly visualized in the left upper quadrant that are nonspecific and not entirely evaluated . The partly visualized left shoulder shows a substantial degenerative change . Mild degenerative changes affect the thoracic spine .
    OUTPUT:
    
1 . No evidence of acute cardiopulmonary disease . 2 . Mild to moderately distended small bowel in the left upper quadrant . Clinical correlation is suggested . Further imaging could be considered if abdominal pathology is suspected .
