Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lung volumes are low . The heart is at the upper limits of normal size with a left ventricular configuration . There are vague patchy opacities at the lung bases , particularly on the right . In the setting of low lung volumes , these are probably compatible with atelectasis . Projecting over the lingular region is an additional vague opacity which is nonspecific . However , it also appears streaky and may also be due to minor atelectasis . There is no pleural effusion or pneumothorax .
    OUTPUT:
    
Basiliar opacities , likely atelectasis , although evaluation is limited ; repeat radiographs could be considered with better inspiration if there is clinical concern that these may reflect subtle pneumonia .
