Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Portable AP radiograph of the chest demonstrates a right - sided PICC , terminating at the cavoatrial junction . Additionally , there is a nasogastric tube which is seen coursing along the expected location of the esophagus and below the diaphragm , nonacute . A calcified ventriculoperitoneal shunt projects over the right hemithorax . Since the prior study , there has been interval improvement in bilateral pleural effusions , although a small right pleural effusion persists . Multiple vascular clips project over the left axilla and hemithorax . Linear scarring along the left upper mediastinum may be due to prior radiation fibrosis . There is no evidence of pneumothorax . The bilateral hemidiaphragms are flattened , consistent with emphysematous change . Hazy opacification within the right lung base as well as the left lung base is likley due to atelectasis .
    OUTPUT:
    
Bibasilar atelectasis and slight interval improvment in extent of right pleural effusion since the prior study . No evidence of pneumonia .
