Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Assessment of the thorax is slightly limited by patient rotation and low lung volumes . Right internal jugular central venous catheter tip terminates in the upper SVC . No pneumothorax . Heart size remains mildly enlarged . The mediastinal and hilar contours are grossly unchanged . There is crowding of bronchovascular structures with possible mild pulmonary vascular congestion , but no overt pulmonary edema . Patchy atelectasis is noted in the lung bases without focal consolidation . No pleural effusion or pneumothorax is present . Multiple remote left - sided rib fractures are again noted , and spinal fusion hardware spanning the cervicothoracic junction as well as within the lumbar spine is incompletely assessed .
    OUTPUT:
    
Right internal jugular central venous catheter tip in the upper SVC . No pneumothorax .
