From the case: Cavo-atrial junction (chest x-ray)

Annotated image

Normal chest x-ray demonstrating different methods of estimating the position of the cavo-atrial junction:

yellow arrow: two vertebral body levels below the level of the carina
blue arrow: intersection of bronchus intermedius with superior right heart border
red arrow: intersection of the superior right heart border with SVC contour

There are a few methods of estimating the location of the cavo-atrial junction on chest x-ray and they are mostly congruent to a discrete region.
