Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP upright and lateral views of the chest were provided . The lung volumes are quite low , which limit the evaluation . There is crowding of bronchovasculature resulting of the low lung volumes . Given this appearance , a subtle pneumonia is difficult to exclude . No large effusion or pneumothorax is seen . The cardiomediastinal silhouette appears grossly unremarkable , although the patient is rotated to the left , which limits evaluation . The bony structures appear intact .
    OUTPUT:
    
Limited study with low lung volumes . No overt evidence of pneumonia or CHF . If there is strong clinical concern for acute pathology , a repeat is recommended with more optimized technique .
