This coronally reformatted CT scan shows the characteristic short and fat right mainstem that arises at a relatively acute angle off the trachea, such that an aspirated peanut will favor it over the left because of this angle. The left is long and thinner. Courtesy of: Ashley Davidoff, M.D.
In this normal CXR a RUL segmental bronchus and artery are side by side with the lucent air filled bronchus in teal and the artery in royal blue. Note that at this stage they are the same size and they will be for many divisions until they reach the terminal bronchiole.

Heart Failure Kerley B lines
In these images. a nd c are normal and b and d represent thickened interlobular septa in a patient with congestive heart failure. These are the well known Kerley lines, often spoken about but rarely seen. They are identifiedas thin horizontal lines usually seen in the costophrenic angles, not being longer than 2cms in length and touching the pleural surface.
