Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Evaluation is slightly limited due to patient rotation and low inspiratory lung volumes . The cardiac silhouette size is top normal . Mild widening of the mediastinum is stable and likely related to vessel engorgement . Mild pulmonary vascular congestion and pulmonary edema is unchanged . Bibasilar opacities on the left greater than the right are slightly improved from the most recent prior study , possibly reflecting atelectasis . A small left pleural effusion can not be entirely excluded . No significant right pleural effusion is detected . An endotracheal tube is in standard position . A right PICC line is unchanged with the tip terminating in the mid-to - low SVC . A nasogastric tube is seen coursing below the diaphragm and out of view on this image .
    OUTPUT:
    
1 . Improved bibasilar atelectasis on the left greater than the right . 2 . Stable mild pulmonary vascular congestion / edema . 3 . Appropriate position of lines and tubes .
