Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is elevation of the posterior left hemidiaphragm / posterior left diaphragmatic hernia with bowel seen in the lower left hemi thorax . The right lung is hyperinflated suggesting chronic obstructive pulmonary disease . Subtle patchy nodular opacity at the right lung base is seen and could represent small focus of infection or pulmonary nodule . Further evaluation with chest CT is recommended . The aortic knob is prominent and underlying aneurysmal dilatation may be present , which can also be further assessed on CT . Aortic calcifications are seen . The cardiac silhouette is not enlarged . No pneumothorax seen . Evidence of DISH is seen along the spine . .
    OUTPUT:
    
Findings suggesting posterior left diaphragmatic hernia with bowel projecting over the left lower hemi thorax versus elevation of the posterior left diaphragm . Subtle patchy opacity at the lateral right lung base could be due to small focus of infection or pulmonary nodule Aortic knob appears dilated raising concern for aortic dilatation . Above findings can be further assessed on chest CT .
