    INPUT: Left subclavian porta catheter remains in standard position . Cardiomediastinal contours are within normal limits and without change . Lungs are clear except for a focal linear area of atelectasis at the left lung base . Questionable small left pleural effusion manifested by slight blunting of lateral left costophrenic sulcus . Pleural surfaces are otherwise clear . No acute skeletal findings .
    OUTPUT:
    
1 . No radiographic findings to suggest gemcitabine pulmonary toxicity . However , high - resolution chest CT would be more sensitive and may be considered for more complete assessment if clinical suspicion for this entity persists . 2 . Focal left lower lobe linear atelectasis and possible small pleural effusion .
