mild centrilobular emphysematous changes predominantly in the upper lobes

Hi , and welcome! I see you are a new member here, having joined today, much earlier in the morning. We are glad to see you are already engaging with the community through this, your first post.
You may be aware we cannot provide medical advice or diagnostics over the internet (for your own safety), but your concern certainly warrants a reply.
Generally speaking, chest xrays, ordered by one's physician, are then evaluated with a written narrative (for the ordering physician), by a doctor who specializes in radiology. This written explanation is provided to the ordering physician. It is then that physician's responsibility to explain the results to the patient, in this case, you.
My suggestion would be for you to reach out for your physician. The doctor will provide you with the analysis you are looking for. What do you think?
Please do check back and let us know how this turns out for you.
All the best,

If you google what you are asking, that might get you some sort of answer. Sorry couldn't be any further help.
