Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . There are low lung volumes limiting assessment . Given this , increased interstitial markings are again seen including in the right upper lobe where there was previously pneumonia . Findings could be due to infection and / or mild interstitial edema . No pleural effusion or pneumothorax is seen . The cardiac and mediastinal silhouettes are stable given differences in inspiration .
    OUTPUT:
    
Low lung volumes which accentuate the bronchovascular markings and limit assessment . Increased markings diffusely bilaterally could in part be due to low lung volumes and AP technique ; however , infection or interstitial edema is not excluded . More focal opacity in the right upper to mid lung may be due to underlying pneumonia .
