Hi,
The feasibility of the FNA would depend on the proximity of the nodule to either the chest wall or to a large airway. If it is near the chest wall, the needle would puncture through the chest and this could be done with either a CT or an ultrasound guide. The persons who perform this may be the pulmonologist, in other places an interventional radiologist. If the nodule is nearer a large airway then it can be approached via bronchoscopy, the transbronchial biopsy could be the better option (this would usually be done by the pulmonologist).
