Did they just do a HIDA scan, or did they do a HIDA scan with CCK injection? I had my gallbladder removed on Friday, and my HIDA scan was normal (e.g the isotope traveled from my liver, to gallbladder, to small intestine in the appropriate time periods. However, in the second phase of the test, they injected the CCK to cause my gallbladder to contract and expel its contents (as it would after a meal) and it did so maximally at 8.3% after 6 minutes. So, what I'm getting at is that I had a NORMAL HIDA scan, but a very ABNORMAL ejection fraction. If they didn't do the second part of the test with the CCK, insist that they do it. This will tell the story as to how well your gallbladder functions.
