I had a barium swallow x-ray the other day and the doctor who did it said that everything looked fine. I am now worrying though because I'm not sure if I swallowed enough barium! He said to take a big gulp but I found that really hard and I was having quite a small swallow of it, really. So now I'm worried that I didn't swallow enough barium to coat the inside of my throat and so the x-ray might have missed something (I think the x-ray only shows up parts of your throat that is coated in barium?)
So my question is - would the radiographer have been able to tell if I hadn't swallowed enough barium?
