    INPUT: Lordotic positioning . A right - sided internal jugular catheter is seen , terminating in the mid SVC . Left - sided pacemaker is identified . Probable background hyperinflation . The cardiac silhouette is probably slightly enlarged . The pulmonary vasculature is somewhat centrally congested . Hazy bilateral opacities are noted . Lung bases are not entirely imaged . Allowing for this , no frank consolidation is detected . No gross effusions are seen . No obvious pneumothorax is identified .
    OUTPUT:
    
Right internal jugular catheter terminates in the mid SVC . No obvious pneumothorax identified . Probable COPD . Mild cardiomegaly . Vascular congestion with possible hazy opacities at the bases . s
