Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are markedly low . This accentuates the size of the cardiac silhouette which is borderline enlarged . Crowding of the bronchovascular structures is noted without overt pulmonary edema . Streaky bibasilar opacities likely reflect areas of atelectasis . No focal consolidation or pleural effusion is seen . Assessment of the left apex is limited as the patient 's chin and neck obscure this region . No right pneumothorax is seen . There are no acute osseous abnormalities .
    OUTPUT:
    
Limited study due to low lung volumes and patient positioning . Bibasilar atelectasis . No gross intrathoracic abnormality otherwise demonstrated however assessment of the left apex is markedly limited .
