Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . There are low lung volumes . Bibasilar atelectasis is seen . No focal consolidation , pleural effusion , evidence of pneumothorax is seen . Cardiac and mediastinal silhouettes are similar . The ascending aorta appears slightly more prominent , which may relate to low lung volume ; however , followup frontal radiograph with better inspiration or CT with contrast can be obtained to assess aortic diameter . Evidence of DISH is seen along the spine .
    OUTPUT:
    
1 . No acute cardiopulmonary process . Minimal bibasilar atelectasis . 2 . The ascending aorta appears slightly more prominent as compared to the prior study , which may relate to low lung volumes ; however , this could be further evaluated with repeat PA upright radiograph with deeper inspiration or CT with contrast .
