I keep reading that when emphysema is seen only on CT but not on a pulmonary function test, that it is a foreboding sign and signifies a worse prognosis. My CT scan showed “minimal “emphysema, but my PFT tests were normal. My pulmonologist says that the “blebs” are very minor and past radiologists didn’t even mention them (no they have apparently been there without change for two years). I exercise daily at a good intensity, eat well and live a very healthy life. But I can’t shake the sense of trepidation about what was seen on my CT (“minimal emphysema”).
Is this true? Is emphysema that is seen on CT but without corresponding physical symptoms and without corresponding PFT tests signify a worse prognosis?
