Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are very low . Patchy infiltrates in the right and left upper lung are mostly unchanged from the prior study . These findings correlate to the multifocal ground - glass opacities seen on CT chest from two days prior , likely multifocal pneumonia or hemorrhage . A right internal jugular line is seen in the distal SVC , unchanged . NG tube has been removed . Cardiomediastinal silhouette is unchanged .
    OUTPUT:
    
Patchy opacities in the upper lung zones correlate to multifocal ground - glass opacities seen on CT chest , likely infection versus hemorrhage and less likely septic emboli .
