Welcome to Mayo Clinic Connect!
Any lung nodules seem to be confusing. Having RA adds another factor to consider.
I think it’s great that you have been seen at Duke!
As to which CT to do I would have it done at Duke.
After the CT you will get the result the same visit and get an opportunity to discuss options with the Pulmonologist.
I have been followed for pulmonary nodules for 2-3 years now. The last CT showed one had grown and looked suspicious for adenocarcinoma.
I’m having a biopsy in a week.
In general, most lung nodules are benign.
I’m sure Duke is going to help you making a decision.
