    INPUT: Low lung volumes persists . Heart size remains mildly enlarged . Mediastinal and hilar contours are unremarkable . Crowding of the bronchovascular structures is re - demonstrated with probable mild pulmonary vascular congestion . Patchy opacities in the lung bases likely reflect areas of atelectasis , and are not substantially changed in the interval .

Please note that the lung apices are somewhat obscured by the patient 's neck soft tissues projecting over these regions . No acute osseous abnormality is detected .
    OUTPUT:
