Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An ET tube is present . Level of the ETT tip is difficult to determine given obscuration by spinal fixation hardware . The tube can not be traced beyond level of the thoracic inlet on this film . NG tube present , tip extending beneath diaphragm , off film . Left IJ Swan - Ganz catheter present , tip overlying the pulmonary outflow tract . Bilateral chest tubes . No pneumothorax detected . Mediastinal drains are likely present . Note made of prosthetic valves , unchanged . Allowing for differences in positioning , the cardiomediastinal silhouette is probably unchanged . Again seen is diffuse opacity in both lungs and dense retrocardiac opacity with obscuration left hemidiaphragm . The right hemidiaphragm is also not well delineated . Small pleural effusions would be difficult to exclude . Background scoliosis noted , not fully evaluated .
    OUTPUT:
    
Exact position of the ET tube is difficult to determine due to obscuration by overlying hardware . ET tube can not be traced beyond level of the thoracic inlet , but its exact position is not conclusively determined on this film . If clinically indicated , oblique or lateral views , which would project the spinal hardware way from the mediastinum / trachea , could help for further evaluation of the ET tube position . CHF , with vascular blurring and scattered foci of alveolar edema . This is probably slightly worse compared with ___ . Bibasilar opacity , consistent with bibasilar collapse and / or consolidation . At the left lung base , this is unchanged . At the right lung base , this is more pronounced compared with 2 days prior . Possibility of small bilateral pleural effusions can not be excluded .
