Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An ET tube is present , tip approximately 4 .4 cm above the carina . An NG tube is present , tip extending beneath diaphragm to overlie the expected site of the gastric fundus . Right IJ central line tip overlies the distal SVC . No pneumothorax is detected . The cardiomediastinal silhouette is probably unchanged , allowing for technical differences . The right hemidiaphragm remains elevated compared to the left . There is mild vascular plethora and slight blurring , which is probably not significantly changed allowing for technique . There is subsegmental atelectasis at the left and right bases , similar to the prior study . Probable small left effusion .
    OUTPUT:
    
Appearance is overall similar to the prior study , with mild vascular plethora , bibasilar subsegmental atelectasis , and small left pleural effusion . No evidence for interval worsening of the right lower lobe opacity .
