No not a barium tablet esophagram. A video swallow study where you actually eat food... apple sauce, crackers, drink and watch how you swallow. It showed I had a weak swallow and food was not going down all the way. Explained it like a toilet flushing.. Instead of a nice strong flush.. it was weak where it didn't all go down.. and had to swallow a few times or have a drink to rinse it all down.
