Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Assessment is limited due to the patient 's kyphotic positioning , rotation , and low lung volumes . Additionally , soft tissues of the neck obscure evaluation of the lung apices . Given these limitations , the heart size appears grossly unchanged , and mildly enlarged . The aorta remains tortuous and diffusely calcified . Known aneurysmal dilatation of the descending thoracic aorta is not well assessed on the current views . Crowding of the bronchovascular structures is present , and there appears to be mild pulmonary vascular congestion . No pleural effusion or pneumothorax is clearly noted . Patchy bibasilar airspace opacities could reflect atelectasis though infection or aspiration is not excluded . Multilevel degenerative changes in the thoracic spine are re - demonstrated .
    OUTPUT:
    
Limited exam due to patient positioning . Low lung volumes with mild pulmonary vascular congestion and probable bibasilar atelectasis though infection or aspiration can not be excluded . Recommend repeat radiographs when the patient is able to for better assessment .
