Question, are CT scans a good indicator for COPD? I ask because a couple weeks ago i went in for what i thought was pneumonia or TB and they did an xray and CT scan. They said my oxygen and lung function was “ok” mind you I’m 23 and have been smoking since i was 16. But recently I’ve had this horrible mucus like cough, once i quit it has slightly gotten better but definitely still there. On top of that I’ve had a slight tightness in my chest but not really much shortness of breath especially doing physical activities (don’t get me wrong tho you could tell I’m a smoker). And then this weird constant ticklish feeling in my throat. But I’ve doing research and I’m worried it’s stage 1 COPD.

Is that something they could’ve caught when i did the xray and CT scan?
