                        I believe this may be the same as a   hepatobiliary scan.  If so, I had this   done in December of '98.  After an inj-  ection of nuclear fluid, your body is   scanned to watch for activity in the   liver, gallbladder, intestines, etc.    It is a relatively non-invasive,   nonpainful procedure with one exception.    It may recreate the type of symptoms   you have been having.  For me, it was   extreme nausea, but very little pain;   more discomfort really.  This is how   they found that my gallbladder had just   stopped functioning.  All blood work   was normal, ultrasound was normal.    Thank God I worked for a physician who   believed me when I said for some reason   I thought my problem was my gallbladder.   If he had not been persistent on my behalf  I'd still be nauseated because the surgeon  I saw did not believe my symptoms were  from my gallbladder.  The Dr. I worked  for practically had to insist the surgeon  do this scan. Good luck!
