CT scan? I was diagnosed with moderate copd on the basis of a breathing test last summer.

I was diagnosed with moderate copd on the basis of a breathing test last summer. X-ray at rhe time disnt show anything.

Neither my GP nor the respirologist I had one appt with said I need a CT scan done. (GP is worried about radiation exposure)

How do you know exactly what you have if you dont have a baseline scan done of your chest? I see people talk specifically about emphysema, chronic bronchitis, bronchiestasis, etc....all under the umbrella of copd. Sorry if this is a silly question, but wouldnt it be important to get a ct scan done to see exactly what your condition is, or are is everything under the copd umbrella treated by symptoms? I am currently on spiriva respimat and cough up phlegm at points during the day (I exercise a lot and use an aerobika and huff breathing to clear it out).
