I have not. But probably should do that as well as an endoscopy test. Those are the last tests I will probably need to do for a while as I’ve had and mri for my brain and ct scan for the body. The radiologist notes “minimal areas of dependent atelectasis on both lower lobes” but both pulmonologists said that’s because as your lying the Ct image captures you lungs compressed. Both drs were completely unconcerned about that note since my spirometry breath test showed normal. So so frustrating.
