Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There are low inspiratory volumes . The minor fissure is retracted , suggesting atelectasis in the right upper zone . Minimal patchy opacity at both lung bases likely represents atelectasis , but an early aspiration pneumonia or other pneumonic infiltrate can not be entirely excluded . No frank consolidation or air bronchograms identified . No gross effusion . Apparent vascular plethora is likely an artifact of low inspiratory volumes . The cardiomediastinal silhouette is also prominent , but likely accentuated by low lung volumes .
    OUTPUT:
    
1 . Retraction of minor fissure suggests atelectasis in the right upper zone , of uncertain etiology . 2 . Probable atelectasis both lung bases , with low lung volumes . Early infectious infiltrate or aspiration pneumonitis is considered less likely , but remains in the differential . 3 . Prominence of the cardiomediastinal silhouette and vascular markings , likely accentuated by low inspiratory volumes . 4 . Recommend repeat assessment after resolution of acute symptom with chest x-ray obtained with good inspiration , to better assess the cardiomediastinal silhouette and lung bases and to assess for any persistence of the right upper zone atelectasis .
