    INPUT: Frontal and lateral radiographs of the chest were acquired . Lung volumes are slightly low . There is an increase in the bronchovascular markings in both lower lungs , best appreciated on the frontal projection , likely secondary to bronchovascular crowding in the setting of low lung volumes . There is no focal consolidation . The heart appears prominent on the frontal projection , although is suboptimally assessed given the low lung volumes . There are no pleural effusions . No pneumothorax is seen . The mediastinal contours are normal .
    OUTPUT:
    
Increased bronchovascular markings in both lower lungs , likely related to bronchovascular crowding in the setting of low lung volumes . No focal consolidation .
