Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Rotated lordotic positioning . An ET tube is present , tip approximately 3 .6 cm above the carina . An OG tube is present , tip and side - port overlying the stomach . A left subclavian PICC line tip overlies the region of the cavoatrial junction . No pneumothorax is detected . Allowing for differences in positioning , the cardiomediastinal silhouette is grossly unchanged . Again seen is left lower lobe collapse and / or consolidation . A small left effusion can not be excluded . There is upper zone redistribution and mild vascular blurring , similar to the prior film , without overt CHF . On the right , no focal infiltrate or effusion is detected . The previously seen dense band at the right base has resolved . Adjacent in the soft tissues lateral to the mid left chest wall there is a linear density measuring 9 .7 mm long that appears metallic . It is not known whether this overlies are lies within the patient . Clinical correlation requested . No corresponding density is seen on the chest radiographs from ___ and ___ .
    OUTPUT:
    
OG tube tip and side - port lie below the diaphragm , overlying the stomach . Continued left lower lobe collapse and / or consolidation . A small left effusion can not be excluded . Mild upper zone redistribution and slight vascular blurring , without overt CHF , similar to prior . 9 .7 mm metallic density overlying the soft tissues lateral to the left mid chest wall -- ? Artifact overlying the patient versus a new foreign body .
