Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: In comparison to the most recent prior ___ study , there is interval development of a moderate to large sized left pleural effusion with underlying atelectasis or consolidation at the left lung base . Patchy opacification at the right lung predominantly in the lower lung zones most likely represents mild to moderate pulmonary edema , although opacities in the right mid to lower lung are somewhat nodular . No significant pleural effusion is seen in the right hemithorax . No pneumothorax is detected . The pulmonary vasculature is moderately engorged compatible with underlying pulmonary vascular congestion . The cardiac silhouette is incompletely evaluated but likely remains enlarged as seen on the ___ study . Increased prominence of the right paratracheal stripe is likely related to prominent mediastinal vasculature . Aortic calcifications are re-demonstrated . The trachea is midline . Diffuse degenerative changes of the thoracic spine are noted with exuberant costochondral calcification .
    OUTPUT:
    
1 . Interval development of moderate sized left pleural effusion and mild - to - moderate pulmonary edema / vascular congestion suggesting acute heart failure . 2 . Nodular character among diffuse opacities , probably due to heterogeneous involvement with edema ; follow - up radiographs are recommended after diuresis to exclude underlying nodules , however .
