Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared to the prior study , the patient is in true AP position , without rotation . A left IJ central line is present . Allowing for differences in patient rotation , left IJ line tip appears to been retracted slightly compared with the prior film . It now lies slightly to the left of the expected site of confluence of the left brachiocephalic and right subclavian veins . It does not clearly reach the SVC . The opacity in the expected location of the azygous vein measures approximately 6 .6 mm , larger than a normal azygos vein . Overall , the cardiomediastinal silhouette is similar and hazy opacities in both bases are also similar . As before , the right hemidiaphragm is partially obscured and there is dense increased retrocardiac density . There is upper zone redistribution and mild vascular plethora . No pneumothorax detected . ET tube and NG tube again noted .
    OUTPUT:
    
On the current examination , the left IJ line lies slightly proximal to the expected site of confluence of the right subclavian and left brachiocephalic veins and does not appear to reach the SVC . No pneumothorax detected .
