What Affects the Test Reasons you may not be able to have the
test or why the results may not be helpful include: - Pregnancy.
A gallbladder scan is not usually done during pregnancy because
the radiation could damage the developing baby (Reference fetus
Opens New Window). - Barium and bismuth. If a gallbladder scan
is needed, it should be done before any tests that use barium
(such as a Reference barium enema Opens New Window). - The
inability to remain still during the test. - Being allergic to
morphine. |By:||Reference Healthwise Staff||Last Revised:
