Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size is within normal limits , substantially decreased in size compared to the prior exams . The mediastinal contours are normal . Hilar contours have decreased in size , with minimal fullness of the right hila likely reflective of residual lymphadenopathy . Pulmonary vasculature is normal . Linear opacity in the left mid lung field likely reflects atelectasis or scarring . Previously demonstrated diffuse airspace opacities have resolved . No focal consolidation , pleural effusion , or pneumothorax is present . No acute osseous abnormality is visualized .
    OUTPUT:
    
Previously noted diffuse airspace opacities have resolved with only minimal residual atelectasis or scarring in the left mid lung field . No new focal consolidation . No pulmonary edema with normalization of the heart size .
