Hello everyone, I’m a 43 years male and I’m new to this community.
I started to have shortness breath 8 months ago. X-ray shows “hyperexpansion with flattening of hemidiaphragms and blunting posterior sulci”, suspected emphysema, but a CT scan shows clearly lungs. PFT is also normal with FEV1/FVC=71%, DLCO=94%, RV=107%, FEV1 and FVC pred are above 100%.
I feel hard to breath sometimes especially after a big mea, wearing pants with belt. I feel the size of my chest is limiting my breathing, prone position helps a lot.
I failed to breath correctly in CT scan, I inhaled normally and hold while I should take a deep breath and hold. Does this impact emphysema diagnosis on CT
