Thank you en bloc. Your short reply is okay and appreciated. I was hoping that I could maximize the results of the upper gi test. So I could avoid other diagnostic tests.

Does the diaphragm show on chest cat scan, even if its not the focus of the test? I am trying to rule out every possible cause. I asked the doctor about my diaphragm but he said that its normal because if its not it will be "elevated". But you know, when he said this he was already on his way out of the room (on to the next patient). I am not sure if that reply was "reliable" :-).
