Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral radiographs of the chest were acquired . The lung volumes are markedly low , causing exaggeration of the heart size and accentuation of the pulmonary vasculature . Evaluation of the lateral projections is limited by the patient 's arm positioning . There is no focal consolidation . The heart size is likely within normal limits . The mediastinal contours are normal . There are no pleural effusions . No pneumothorax is seen .
    OUTPUT:
    
Suboptimal study secondary to very low lung volumes . No focal consolidation or acute process in the chest .
