Donnajean, sorry I don't know the answer to your question. Mine was detected on the Xray.
Today I had my barium swallow study done and, according to the therapist, I did not aspirate any liquid or food that I consumed. She therefore, made an assumption that it is probably reflux that is getting into my lungs and is suggesting to the surgeon to prescribe Nexium for me. I don't really mind that, except that it seems that she is taking quite a leap in assuming that reflux is the problem. The only person that ever suggested that I may have reflux was the speech pathologist who looked at a video of my vocal chords back when I was first seen at MDACC.
I don't want to start taking a daily prescription for something that I may not need.
