Hi. Thank you for sharing your personal experience with us here. It is totally understandable to be concerned when you get such a diagnosis. And I am sorry that you are having to go through all of this. I see you received a response from my colleague Barbara above. I want to say that I agree with her 100%. Have you had a chance to look over her suggestions? That said, I do have something to add myself. Based on my 25 plus years experience reviewing x-rays and CTs of patients with COP,D, I am wondering if the terms you mention above -- "centrilobular emphysematous change," "thin-walled pulmonary cysts," and "subpleural linear densities" -- are complex medical terms radiologists use in describing what they see on x-rays or CTs. In other words, I'm thinking they are basically their fancy way of communicating to your doctor that they see that you MAY have COPD. And your doctor can use this information to decide what further tests to order, and how best to adjust your treatment regimen moving forward to get you feeling better. Have you had a chance to talk to your doctor about your concerns here yet? Hope this helps. And wishing you all the best. John. community moderator
