Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are better aerated with interval resolution of the left lower lung collapse . Left lower and mid thoracic rib fractures appear slightly more displaced as compared to prior . Bilateral patchy lung opacities could represent either consolidation or asymmetric edema ; contusion is considered less likely . A very small left apical pneumothorax is noted . Cardiomediastinal silhouette is unchanged given changes in positioning . Multiple contiguous left rib fractures appear more displaced as compared to the previous radiograph of ___
    OUTPUT:
    
1 . Multifocal patchy airspace opacities could represent multifocal aspiration , developing infection , or asymmetrical edema . Contusions is considered less likely given new and progressive course of most of the opacities compared to ___ . 2 . Interval resolution of left lower lung collapse .
