repeated pneumonia can cause scar tissue and inflammation in the lungs, like what is seen on your chest CT Scan.
banding is thicking of the lung tissue which can come from prior lung infections.
dependent are the lower parts of the lungs, atelectasis is mild collapsed lung which doesn't expand well if you didn't take a nice deep breath when you had the chest CT scan done.
mediastinal lymph nodes are normal size at 9mm. these are normal lymph nodes which are there to help filter the lymphatic fluid in the lungs.
as we get older, we can get calcium deposits on the walls of large blood vessels like the aorta. this can be seen on CT scan. best thing is to lower your cholesterol and eat less or no animal fats and a vegan diet to reverse plaques on your arteries.
