Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Right PICC tip terminates in the lower SVC . Lung volumes are low . Heart size is accentuated as a result of low lung volumes , and is likely borderline enlarged . The aorta is unfolded . There is no pulmonary edema . Streaky bibasilar airspace opacities could reflect atelectasis though infection , particularly in the right lung base , is difficult to exclude . Blunting of left costophrenic sulcus is similar compared to the prior exam , and likely attributable to mild pleural thickening . No focal consolidation is identified . There is no pneumothorax . No large pleural effusion is identified . No acute osseous abnormality is seen .
    OUTPUT:
    
Low lung volumes limits assessment of the lung bases . Streaky bibasilar airspace opacities could reflect atelectasis , but infection is difficult to exclude . Recommend repeat radiographs with improved inspiratory effort ( when patient is able to ) for further assessment .
