Hi, I'm just wanting some help understanding my non contrast CT scan result. It says moderate scarring at both pulmonary apices, additional one 3.6mm sub-solid subpleural nodule right lower lobe. No pleural or pericardial effusions. Central airways patent. I've had a chronic barking cough and am an occasional smoker and ex full time smoker (never again!). I am being sent to a Pulmanologist who is booked out till next January but is seeing me in two weeks so now I'm even more nervous. Thanks for your help.
