Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Right pleural effusion is improved . Left basilar opacity likely reflects combination of moderate pleural effusion and possible atelectasis or consolidation . There is new fluid in the minor fissure . Moderate cardiomegaly is stable . There is mild central pulmonary vascular congestion but pulmonary edema is significantly improved . The mediastinal and hilar contours are normal . There is calcification of the aortic knob . There is no pneumothorax .
    OUTPUT:
    
1 . Significant improvement of pulmonary edema . Stable moderate cardiomegaly . 2 . Worsening opacity at the left base may reflect atelectasis . Pneumonia is felt less likely but can not be completely excluded in the appropriate clinical setting . 3 . Small right pleural effusion is smaller and moderate left pleural effusion is unchanged .
