Lengthwise vs. Crosswise Chest X-rays
I can attest that a majority of x-rays done especially on males are usually done crosswise. There is a debaucle over this and it is preferred that all chest x-rays should be done lengthwise thus some of the anatomy being cut off and a repeat to be done. Is there really a difference in the projections as long as all the anotomy is there?

I'm radiologist reporting different examinations, it doesn't matter which projection is obtained as long as I can assess the lung apex and both C/P angles.
usually the chest x-ray is performed using the transverse width of the film, and using the longitudinal mainly with tall persons..for both..all I need is the anatomical details, so both are accepted.

It all depends on the Hospital-Clinic routine but on my experienced I encountered lots of chest routine done in lengthwise, few only for crosswise. The lengthwise mostly preferred for slim-tall type of person while for crosswise heavy obese type person. For practical points, there should be an allowance 2" or 5cm top edge of cassette and 1/2 or 1" lateral border when positioning a Chest PA routine to compensate the expansion of the lungs as well as the ribs.

When in doubt, do the case crosswise.
In general, all men are done crosswise unless, it is a no brainer.
All women are done lengthwise even large women.

You are correct, it makes no difference.
The complete anatomy of the chest is the goal.

mentioning your name; in my last reply.
