    INPUT: The lung volumes are low . This is accentuating the cardiomediastinal silhouette , although there is likely moderate - to - severe cardiomegaly . The mediastinum is prominent , which could be due to technique . A right internal jugular catheter is present with the tip in the low SVC . There is no pneumothorax . The lungs are clear without consolidation or edema . There is no pleural effusion .
    OUTPUT:
    
1 . Right internal jugular catheter with tip in the low SVC . 2 . Probable moderate - to - severe cardiomegaly . 3 . Minimally widened mediastinal contours , which is likely due to technique , although if clinical concern is present for aortic pathology , could further evaluate with a CT of the chest .
