Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP and lateral views of the chest . Patient is rotated to the left , somewhat limiting exam . Previously seen right PICC is no longer visualized . Blunting of the lateral costophrenic angles is noted which could be due to a fat pad on the left given rotation and atelectasis versus pleural thickening on the right . The known bibasilar pulmonary nodules are better assessed on prior CT scan . Superiorly , the lungs are grossly clear . The cardiomediastinal silhouette has not definitely changed given differences in positioning . Posterior thoracic fixation hardware is again seen .
    OUTPUT:
    
No definite acute cardiopulmonary process .
