I currently live in a New York suburb about 50 miles outside of NYC. My motility doctor is located in Valhalla NY and is affiliated with Westchester Medical Center. He gave me a prescription for a 4 hour gastric emptying scan, but I can't seem to find a hospital in the area that does the 4 hour GES - they all do 90 minute and 2 hour GES, which I have already had. I had the 90 minute test in February, but now that I have been able to see a motility specilaist, he does not belive the 90 minute tests are accurate, and wants me to get the 4 hour test instead. Does anybody know of a facility that will do the 4 hour test in my area? My doctor's hospital doesn't do it, and my doc is on vacation for a while, so I can't ask him to recommend another place, and his office can't give me any guidance. I know I could probably find a place in NYC if I had to, but I would like to avoid doing it in NYC if I could.
